Not sure what El is, but you should look for errors in the oacore logs in $INST_TOP/logs/ora/10.1.3/j2ee/oacore/oacore_default_group_1.
That's a typo. Should be IE (Internet explorer).
In taht directory in log.xml we have:
<MSG_TEXT>Internal error raised tyring to instantiate web-application: ascontrol defined in web site OC4J 10g (10.1.3) Default Web Site. Application: ascontrol does not exist. Error creating Web application: ascontrol</MSG_TEXT>
17/05/05 16:13:24.584 html: chain failed
javax.servlet.ServletException: Could not initialize class oracle.apps.fnd.functionSecurity.User
I recommend increasing oacore Xmx and Xms and run autoconfig:
Unable To Login After Clone (Doc ID 418130.1)
JVMs are having Out Of Memory issues and throwing java.lang.NullPointerException errors after upgrading to 12.1.3 (Doc ID 1435059.1)

Also ensure all OS prerequisites have been met especially in /etc/security/limits.conf:
Oracle E-Business Suite Installation and Upgrade Notes Release 12 (12.1.1) for Linux x86-64 (Doc ID 761566.1)
I'm agree to increas oacore Xmx and Xms and run autoconfig. From which document does come this suggestion?
In the documents you mentionned above I do not see any relevance with http 500 or ProcessorException or .java:517.
We have not clonned it. We have just relocated database (RAC one node) to a new server and then came back to the original server.
It has been working with the same Xmx and Xms on the same server.
There are two other EBS system that work fine on the same server.
Mostly from 20 years Apps DBA experience.
If you have multiple systems running from the same OS account, you should increase ulimits from those in the doc. I set all limits to 65536 except stack which I set to 262144 and memlock which is half the RAM on the box.
For Xmx/Xms recommendations, you can look at the following OOW doc:
Getting Optimal Performance from Oracle E-Business Suite [CON6711]
Finally it is working now without any action but stop start the application and DB on sunday.
Thanks and regards.
