What about your system performance like CPU utilization, Memory and paging?

Its the same application crashing again and again.
try to set the ulimit for stack and data to: unlimited. May be this will help.
If not, then generate the snapcore from the directory where system dumped the core, which is /usr/lpp/tsd/tsdserv/core in your case.
This will produce .pax.Z file in /tmp/snapcore directory.
Send this file to IBM for analysis.

What about your system performance like CPU utilization, Memory and paging?
A) Till now not noticed any thing of this sort of problems in 5.3.May I know the reason for asking this.
