This document has been merged with E-RD: PSDSTSRV Service Crashes With Error "PSPAL: Abort: Location: /vob/peopletools/src/pspal/exception_sigaction.cpp" In AIX 6.1 Process Scheduler (Doc ID 1335930.1).


On PeopleTools 8.49 version, upgraded to AIX 6.1 operating system for the Process Scheduler. When attempting to post files, the Distribution Server dumps and throws the following:

1)  process_state.txt

Exception context:
Signal: (11) SIGSEGV - Segmentation fault

Signal information:
    Signal was generated by the kernel
    si_signo=11      (SIGSEGV - Segmentation fault)
    si_code=51       (invalid permissions for mapped object)

2) In the Distribution Agent log file, psdstagnt_mmdd.log, it shows:

"PSDSTSRV.10879208 (1) [05/14/11 00:58:41 PostReport](4) (JavaHttp): Java VM Created.
PSDSTSRV.10879208 (1) [05/14/11 00:58:41 PostReport](4) (JavaHttp): Unhandled exception
Type=Segmentation error vmState=0x00000000

PSDSTSRV.10879208 (1) [05/14/11 00:58:41 PostReport](4) (JavaHttp): CPU=ppc64 (12 logical CPUs) (0x600000000 RAM)

PSPAL: Abort: Unexpected signal received
PSPAL: Abort: Location: /vob/peopletools/src/pspal/exception_sigaction.cpp:518: PSPAL::SigactionSignalHandler::RecoverableSignalHandler(int, siginfo_t *, void *)"

The issue can be reproduced at will with the following steps:
1. Start the Process Scheduler.
2.  Observe the distribution agent crashes immediately.

It was found that even pointing the JRE to the PeopleTools delivered library did not resolve the issue.
Example: JavaVM Shared Library=<PS_HOME>/jre/bin/classic/libjvm.a.

Due to this issue, users cannot view any of process report output files sent to the WEB.


Upgrade the Process Scheduler operating system to AIX 6.1.
