Hi,
I'm using MQ Series v5.2 on solaris. My application is multi threaded and in my MQGet method, if there is no data found I close my connection and open it again. And there is no wait time specified in the program. If my process runs for some time, then it generates a coredump and terminates.
The content is:
SIGSEGV 11 segmentation violation
si_signo [11]: SEGV
si_errno [0]:
si_code [1]: SEGV_MAPERR [addr: 0x0]

| My initial guess would be that you are running out of resources because java garbage collection isn't running. Were there any *.FDC files produced along with the core? |
