Solaris 10 performance - process.max-stack-size exceeded by process

Our PrimePower 850 server runs Solaris 10 (kernel 127127-11) and
Symantec Storage Foundation for Oracle 5.0-mp1. The Websphere
application runs with Oracle 10g database. We are having issue with
slow performance on our application. The OS/hardware seem OK.
However, we are getting the following alerts repeatedly in the
messages file. There's no project, resource or task setup in solaris
10 for this server. Any idea where the alerts are coming from and how
we can resovle this.

Thanks, Bill

Well it looks as if Solaris thinks that the stack has overflowed in the
above mentioned processes. This is VERY suggestive of a programming error!

It could also be due to the maximum stack size being set too small.
Someone will have to determine whether to fix the program or increase
the maximum stack size. This will probably require that someone find
out what the process is doing with all that stack space!
