500 errors that do not match with application server

Hi,

I have been having some weird 500 errors showing up in my SJSWS access logs. The number of these errors are inordinately high (more than a hundred HTTP 500s counts as abnormal to me). All of these errors are on URLs that are reverse proxied to application servers behind them. Yet, when I check on the access / application logs on the application server, all of these requests are returned as normal HTTP 200.

I suspect that these errors are somehow due to the connection between the web server and application server being reset but I have no way of confirming this. Right now, I'm stuck as far as troubleshooting is concerned. Server.log in SJSWS does not indicate anything out of the ordinary either.

Is there anyone who was come across this before or has any pointers on how to troubleshoot any further?

Thanks,
Wong

    My infra setup is as follows:

    Tier 1: Cisco Content Switch load balancer, load balancing between:
    Tier 2: 2 units of T1000 web servers running SJSWS, each of which hosts static content and reverse proxies/load balances between:
    Tier 3: 2 units of V890 app servers running both Tomcat and Glassfish on separate ports

    Roughly looks like this visually:
              LB
             /  \
            /    \
          Web    Web
           |\    /|
           | \  / |
           |  \/  |
           |  /\  |
           | /  \ |
           |/    \|
          App    App
    I have encountered absolutely no such errors reverse proxying to the Tomcat applications; all the 500 errors that occur are pointed to the Glassfish instance.

    Reverse proxy configuration is done using standard SJSWS RP configurations (2 IP addresses configured pointing to each of the app servers).

    Some more information:

    HTTP Listener configuration on T1000 web servers:
      <http-listener>
        <name>http-listener-8181</name>
        <port>8181</port>
        <acceptor-threads>32</acceptor-threads>
        <server-name>cm-web01</server-name>
        <listen-queue-size>32768</listen-queue-size>
        <default-virtual-server-name>CM-web01</default-virtual-server-name>
        <ssl>
          <server-cert-nickname>securelogin.cimbbizchannel.com</server-cert-nickname>
          <ssl2-ciphers/>
          <ssl3-tls-ciphers/>
          <client-auth>required</client-auth>
        </ssl>
      </http-listener>
    Keep alive settings under Virtual Server is pretty much default (enabled, default number of threads and max connections, 30 seconds timeout, 0.001 poll interval).

    Thread pool settings under Virtual Server is enabled, max threads 512, min threads 128, stack size 131072, queue size default.

    Oh, and SJSWS version/build number is 7.0U2 B12/09/2007 09:02.

    Please let me know if any other information is needed.

    Thanks!

    I assume this is not happening for every request, such problems are harder to debug. Can you run the server in <log-level>finest</log-level> and trace one request which returns 500 Internal error and let me know if you get any information?

    I'd probably be installing Apache right now if it happened for every request so you're right :)

    Have turned on finest logging, but what do you mean exactly by "trace"?

    Thanks,

    I mean look at the time stamp of that 500 internal request in access logs, almost at the same time the details of that request should have been logged in error logs. So you can get an idea of at which section of error logs are relevant. If you can see anything in that section that shows why we are getting 500 internal server error it would be great.

    Thanks, was doing just that. Didn't take long to come out with some results. Here it is. I reckon that the parts that says REQ_ABORTED is where I should be looking at but I'm not too familiar with how to interpret this yet. Where should I be reading?

    Yes, If a SAF returns REQ_ABORTED it means there is a problem error SAFS should be called. More info in NSAPI programmers guide:
    http://docs.sun.com/app/docs/doc/820-1064/abvdy?l=en&a=view&q=REQ_ABORTED

    In your logs, I see these lines :
    [28/Jan/2008:15:21:42] fine (18752): for host 60.50.39.219 trying to GET /bizbanking/searchCAFCAtransHistory.action, reusing existing persistent connection to cm-app02:8081
    
    [28/Jan/2008:15:21:47] fine (18752): for host 60.50.39.219 trying to GET /bizbanking/searchCAFCAtransHistory.action, service-http reports: HTTP7763: client disconnected before remote server responded
    See there is a 5 seconds gap between the two, wonder what happened. It says client (means your other server) disconnected. Can you see this app. server's log at that time?

    Argh, then I reckon I need to turn on server.log to finest on the app server as well. Will do so now. Here's to hoping that Glassfish doesn't need a restart to modify log levels. It seems to have a glass jaw compared to SJSWS, configuration-wise.

    Hi,

    At current log levels, there's nothing much to find in the app server logs. Even my application logs (based on log4j) doesn't throw up any information at all. Access logs return a very normal 200 response.

    I'm a bit reluctant to turn on finest logging during peak hours as it really slows down the server like heck. Is there a specific module that I should be changing the log levels for?

    But I suspect that there's not much to find out though. I have checked the access logs and they show a perfectly normal response.

    Is it possible that it's not the app server terminating the request but it was terminated from the client (i.e. web server( instead?

    Thanks,
    Wong

    Our web server is disconnecting as it was waiting for headers from the remote server. Problem could be at either end.

    Can you set "timeout" and "poll-interval" from 5 seconds to more it may help.

    http://docs.sun.com/app/docs/doc/820-1062/gdhrg?l=en&a=view has an example
    ObjectType fn="http-client-config" keep-alive="false"

    Can you try
    ObjectType fn="http-client-config" keep-alive="false" timeout="60" poll-interval="20"
    Not so sure if it will take timeout and poll-interval this way.

    Worst case can you disable keep alive in the whole server and check?

    Are you using 7.0u2?

    Web Server reported that the "client disconnected before remote server responded", so I imagine that's exactly what happened: the end user requested a page that took a long time load and clicked the Back or Reload button in their browser. Web Server noticed that the client had gone away and stopped waiting for the Application Server to respond.

    It's probably a bug that Web Server treats such responses as 500 Server Error responses, but it's kind of moot because the client isn't around to see them.

    Thanx Elving. Its failing around :
    // Did the client go away?
    if (!net_isalive(sn->csd)) {
    ... so I guess its the client's (browser) socket.

    Comments in the code say :
    * if sn->csd polls ready for reading but there's no data available to be read, the user
    * probably got tired of waiting for a slow origin server.

    Hi Elving,

    It's possible that what you described happened, but does not seem very likely given the patterns shown in the access logs. For e.g.:
    [28/Jan/2008:18:00:18 +0800] - 210.187.118.178 - [serialNumber=620525106500,CN=XXX XXX XXXXX,OU=333510P,O=XXXXXXX XXXXXXXXXXX XXX XXX,C=MY] - "GET /myapp/myAction.action?selectedAccount=10019309&spefDate=&selectedDate=6&d-3490878-p=2&y=15&x=24 HTTP/1.1" "https://www.mydomain.com/myapp/myAction.action" 500 11197
    [28/Jan/2008:18:00:28 +0800] - 210.187.118.178 - [serialNumber=620525106500,CN=XXX XXX XXXXX,OU=333510P,O=XXXXXXX XXXXXXXXXXX XXX XXX,C=MY] - "GET /myapp/myAction.action?selectedAccount=10019309&spefDate=&selectedDate=6&d-3490878-p=2&y=15&x=24 HTTP/1.1" "https://www.mydomain.com/myapp/myAction.action" 500 11197
    [28/Jan/2008:18:00:48 +0800] - 210.187.118.178 - [serialNumber=620525106500,CN=XXX XXX XXXXX,OU=333510P,O=XXXXXXX XXXXXXXXXXX XXX XXX,C=MY] - "GET /myapp/myAction.action?selectedAccount=10019309&spefDate=&selectedDate=6&d-3490878-p=2&y=15&x=24 HTTP/1.1" "https://www.mydomain.com/myapp/myAction.action" 500 11197
    Please pardon the format, I had custom formatted it as follows:
    [%SYSDATE%] - %Ses->client.ip% - [%Ses->client.user_dn%] - "%Req->reqpb.clf-request%" "%Req->headers.referer%" %Req->srvhdrs.clf-status% %Req->srvhdrs.content-length%
    Even given users' impatience, it seems hardly likely that they would click stop/refresh in just 10 seconds (the time gap between the 1st and 2nd lines of the log).

    Another example would be:
    [28/Jan/2008:17:25:19 +0800] - 60.50.231.92 - [serialNumber=650525045194,CN=XXXXX XXXXXX XXXXXX,OU=MA0080518X,O=XXXXX XXXXXX XXXXXX,C=MY] - "GET /myapp/myAction.action HTTP/1.1" "https://www.mydomain.com/myApp2/start.do" 500 11197
    [28/Jan/2008:17:25:20 +0800] - 60.50.231.92 - [serialNumber=650525045194,CN=XXXXX XXXXXX XXXXXX,OU=MA0080518X,O=XXXXX XXXXXX XXXXXX,C=MY] - "GET /myapp/myAction.action HTTP/1.1" "https://www.mydomain.com/myApp2/start.do" 500 11197
    That's just 1 second between the 1st and 2nd requests. A double click would be less than 1 second. It's as if the web server immediately returned a 500 upon receiving the request. But then, it may be that the user had absent-mindedly clicked another time while waiting for the response to come back.

    Is it possible for the web server to record how long it took for the request to be processed? At least I would have a reference point. I had been wanting something like this like forever, be it Apache, IIS or SJSWS :)

    Thanks,
    Wong

    Hi mv,

    I've switched off keep alive in SJSWS' http client settings, but it I've still gotten about 25 HTTP 500s in this same manner seems then. Elving's hypothesis does seem to have some merit as the pages affected involves massive queries and parsing and usually take up at least 10-30 seconds of processing before returning a response.

    It's frustrating to not be able to pinpoint what the user was doing though, and I'm pretty darned sure when my client gets around to looking into the access logs, he's going to give me hell for the number of HTTP 500s in them. Perception-wise, it's difficult to fight the gut feeling this gives that the application is throwing errors.

    Thanks,
    Wong
