Thank you for the suggestion. Unfortunately while it claims that it dumped a core, strangely I can't find it! At first I thought the limits had been set (as in ulimit -c 0).
[michael@blackbox test]$ ulimit -a core file size (blocks, -c) 10000 data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited pending signals (-i) 31488 max locked memory (kbytes, -l) 64 max memory size (kbytes, -m) unlimited open files (-n) 1024 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) 1024 virtual memory (kbytes, -v) unlimited file locks (-x) unlimited But ulimit seems to say its not dumping anything. I will keep on looking. -- View this message in context: http://activemq.2283324.n4.nabble.com/ActiveMQ-CMS-core-dump-tp4130577p4142550.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
