AppServer wont boot with PUBSUB=Yes. Failing at:

exec PSPUBDSP -s PSPUBDSP_dflt:Dispatch -- -C psappsrv.cfg -D FS89PRF -S PSPUBDSP_dflt :
        CMDTUX_CAT:1864: INFO: Process ID=479386 Assume failed (pipe).

tmboot: CMDTUX_CAT:827: ERROR: Fatal error encountered; initiating user error handler

This error can occur for several reasons:

1. Resource issues. Semaphores RAM etc.
2. Installation of the Unix box was done by copying a file system rather than installing according to the Peoplesoft installation instructions.

• Run 'ulimit -a' on the Unix Appserver. The results should be unlimited.
• Increase the java heap size on the application server by uncommenting the following line in your psappsrv.cfg

JavaVM Options=-Xmx256m -Xms128m

• Remove the physical libjvm file, and create a symbolic link. Paths below should look as follows:
