Hi Nick, Thanks for replying. I could not get the version, modules and MPM now. But I have the gdb output: (gdb) bt full #0 0xc020c4b0 in kill+0x10 () from /usr/lib/libc.2 No symbol table info available. #1 0x61834 in sig_coredump+0x138 () No symbol table info available. #2 <signal handler called> No symbol table info available. #3 0xc0137b24 in $$dyncall_external+0 () from /usr/lib/libc.2 No symbol table info available. #4 0xc01845b4 in exit+0x74 () from /usr/lib/libc.2 No symbol table info available. #5 0x52cf4 in destroy_and_exit_process+0x80 () No symbol table info available. #6 0x54978 in main+0x12f4 () No symbol table info available. This may be a dumb question, but if I am using apache through the Borland Enterprise Server 5.2.1, how would I be getting the information that you want? Thanks.

Is that happening when you try to shutdown/restart, or at random? And to make a useful report, you'd need to tell us what version, modules, and MPM you're using. -- Nick Kew Application Development with Apache - the Apache Modules Book http://www.apachetutor.org/ --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
