I've trace my problem with STRACE. I make a SIP call with kphone at number
99999. This user is present in the sip.conf file but it isn't registered. After
3 call at this number and making 'stop now' command the process 1525 become
zombie. This is the trace. Asterisk start with PID 1522:

process PID 1522:

clone(child_stack=0x30226bd0,
flags=CLONE_VM|CLONE_FS|CLONE_FILES|CLONE_SIGHAND|0x21) = 1523

wait4(-1, [WIFEXITED(s) && WEXITSTATUS(s) == 0], WNOHANG|__WCLONE, NULL) = 1523
wait4(-1, 0x100c5e98, WNOHANG|__WCLONE, NULL) = -1 ECHILD (No child processes)
exit(0) 

process PID 1523:

--- SIGRT_0 (Unknown signal 32) ---
exit(0)                                 = ?

--- SIGRT_1 (Unknown signal 33) ---
wait4(-1, [WIFSIGNALED(s) && WTERMSIG(s) == SIGSEGV], WNOHANG|__WCLONE, NULL) = 1539

What are the unknown signal 32 and 33 ? Is it a memory problem (32MB of SDRAM) ?
Has anyone any idea ?

Regards,
Arty.
