Woof! We've been seeing core dumps on FreeSWITCH shutdown. I just updated to today's revision (r9526) and still see them: freeswitch: src/switch_core_hash.c:59: switch_core_hash_destroy: Assertion `hash != ((void *)0) && *hash != ((void *)0)' failed. Core was generated by `/usr/local/freeswitch/bin/freeswitch -nc -nf -core'. Program terminated with signal 6, Aborted. #0 0x00110416 in __kernel_vsyscall () (gdb) where #0 0x00110416 in __kernel_vsyscall () #1 0x00b69690 in raise () from /lib/libc.so.6 #2 0x00b6af91 in abort () from /lib/libc.so.6 #3 0x00b6293e in __assert_fail () from /lib/libc.so.6 #4 0x0014c53a in switch_core_hash_destroy (hash=0x2768dc) at src/switch_core_hash.c:59 #5 0x00274bde in mod_console_shutdown () at mod_console.c:345 #6 0x0015e113 in do_shutdown (module=0x9801360, shutdown=SWITCH_FALSE, unload=SWITCH_FALSE) at src/switch_loadable_module.c:1129 #7 0x0015e2b5 in switch_loadable_module_shutdown () at src/switch_loadable_module.c:1158 #8 0x00156b6e in switch_core_destroy () at src/switch_core.c:1344 #9 0x08049b02 in main (argc=4, argv=0xbf85ff54) at src/switch.c:559 This occurs when using "freeswitch -stop", as well as directly sending SIGTERM to the freeswitch process. Fully reproducable. Core files available if you need 'em. Thanks, --Woof!
