PM41133: ProcessOpException might be thrown when terminating a process

Fixes are available

APAR status

Closed as program error.

Error description

The nodeagent trace shows that the process is terminated:

[1/06/11 12:28:50:480 EST] 00000059 NodeAgent > terminate Entry
        WebSphere_Portal2b
.
.
[1/06/11 12:28:50:510 EST] 00000059 NodeAgent     >
sendNotification Entry websphere.process.stopping
        WebSphere_Portal2b
.
[1/06/11 12:28:50:531 EST] 00000059 UnixProcessIm >  terminate()
: Calling for a process termination. Entry
.
[1/06/11 12:28:54:537 EST] 00000059 UnixProcessIm <

waitForTermination() : Done with waiting for process termination
Exit
[1/06/11 12:28:54:537 EST] 00000059 UnixProcessIm <  Terminate()
Exit

NodeAgent calls waitForTermination, and since the process object
is already released, that exception is thrown:

[1/06/11 12:28:54:537 EST] 00000059 UnixProcessIm >

waitForTermination() : Requesting to wait for process

[1/06/11 12:28:54:538 EST] 00000059 NodeAgent     3   Threw

When terminating an application server process, a
ProcessOpException is thrown if the process object is already
released indicating that the process is already released and
no further call is allowed:
Stack Dump = javax.management.MBeanException: null nested
exception is

Problem conclusion

Code has been changed to catch this exception an not throw it
as an AdminException since, when the process object is
released, the process is already terminated.

The fix for this APAR is currently targeted for inclusion in
fix packs 6.1.0.41, 7.0.0.21 and 8.0.0.1. Please refer to the
recommended updates page for delivery information:
http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980.

For V6.0.2, an interim fix will be available upon request.
