Hello,
this one seems from the main process during the shut down cleanup.
Perhaps the core from main process overwritten the one from worker
process. Can you enable one core file per process in Solaris? In linux
is possible via:
echo "1"> /proc/sys/kernel/core_uses_pid
Then you have to reproduce the case and get the backtraces from each
corefile.
Cheers,
Daniel
