Issue/Introduction

 

When running a Policy Server in high load conditions, the Policy
Server restarts on its own.

What are the correct JVM settings in high environment ?

 

Environment

 

Policy Server 12.8SP3 on RedHat 7

 

Cause

 

The backtrace shows a crash in the JVM

pkgapp.backtrace :

  #0  0x00007f4a2d0121f7 in raise () from /lib64/libc.so.6

  (gdb) #0  0x00007f4a2d0121f7 in raise () from /lib64/libc.so.6

The crash seems to happen in the Custom Java code, where common-logger
is in use. At the same time different version of the same .jars are in use like
:

  commons-logging
  gson
  httpclient
  httpcore

In Java code, different versions of the same jars cannot be used. The
ones already given by the Policy Server should only be used.

 

Resolution

 

Instead of using another version of libraries commons-logging and
gson, use the one given by the Policy Server to avoid conflicts :

The jar files from the Policy Server :

  /opt/CA/siteminder/bin/endorsed

instead of these ones :

  /opt/CA/siteminder/mycustomcodejar/commons-logging-1.2.jar:
  /opt/CA/siteminder/mycustomcodejar/gson-2.6.1.jar:
  /opt/CA/siteminder/mycustomcodejar/httpclient-4.3.6.jar:
  /opt/CA/siteminder/mycustomcodejar/httpcore-4.4.10.jar:
