developer studio 12.5 collector crashes with any 64bit 1.8 jvm on linux

nevgeniev

Hi,

Does anyone experience the following (and is there solution available) oracle's developer studio collector tool crashes with any 1.8 (.65-.100) 64bit jvm I've tried on linux

It crashes almost immediately if I don't specify -XX:+PreserveFramePointer... and if that option is set it crashes anyway it just takes longer:

just for those who interested libcollector.so from solaris studio 12.3 works just fine, yet you would have to use er_print from 12.5 to read results

Nikmolchanov-Oracle

Thank you very much for the report. Unfortunately I cannot reproduce the problem on our test systems.

Could you please provide additional information?

1. Linux version

2. H/W information

If you run "perftools_whichami -a", it will print something like this (I replaced the machine name with "xxx"):

Also it would be great to profile the same application. Can you try to profile "analyzer"?

Thanks.

also... it looks like it happens specifically with application I need to profile which is quite complex and involves non-java threads as well

I've tried to run collector on simplistic 'false sharing' java program and everything works just fine.

oracle studio 12.3 didn't crash but doesn't decode java8 stacks unfortunately..

if you could provide me debug version libcollector I should be able to provide you with exact line numbers from __collector_get_frame_info

C  [libcollector.so+0x444ec]

C  [libcollector.so+0x421e7]  __collector_get_frame_info+0x407

C  [libcollector.so+0x4f023]

some more info (function names) based on

objdump -d lib/analyzer/amd64/libcollector.so

Nikmolchanov-Oracle

Thank you very much for the additional information! We do not have such H/W (E5-2667),

but we could probably reproduce the problem on our test systems if we have the same application.

nevgeniev

Ok,

It seems I found a problem... looks like collect fails to parse onload stack frames (solarflare userspace network driver)

Can you check it? The onload version is:

OpenOnload 201509-u1

Copyright 2006-2016 Solarflare Communications, 2002-2005 Level 5 Networks

Built: May 19 2016 12:44:01 (release)

Kernel module: 201509-u1

Nikmolchanov-Oracle

Thank you very much for localizing the problem!

Recently we found and fixed several similar problems in "libcollector.so",

and probably this one is already fixed, but we have to verify it.

Do you know which application I can try to profile to reproduce this bug?

And one more question: I asked my management if we can send you a debug

version of collect and libcolledtor.so to verify that the problem is fixed.

Would you be able to try this development debug version?

Thanks.

Nik

nevgeniev

Hi,

Yes, I would be glad to run debug version of collector/libcollect

I'll try to produce 'demo' program which sends multicast packets and try to run it under onload/collector ... the actual program uses tibco ftl on top of onload, but I don't think ftl contribute anything to the bug as it runs just fine w/o onload

Nikmolchanov-Oracle

I'm still waiting for the answer from our management on my question, so if you can create a demo program - that would be very useful!

Thanks.

Nik

Nikmolchanov-Oracle

I found out that I cannot send my debug version via email, but there is a chance that a special site can be created for you to download the debug version.

To create such site we need some information from you. Can you send me email, and I'll reply with the explanation of what information is needed?

My email: [email protected]

Thanks.

Nik
