[Devel] 100% cpu

[Helge Waastad]

Hi,
I suddenly got 100% cpu usage on my openser processes..

I tried to kill the daemon and heres the backtrace of the remaining
process.

0x0000000000456790 in fm_status (qm=0x5eca60) at mem/f_malloc.c:515
515                     for (f=qm->free_hash[h].first,j=0; f;
(gdb)



(gdb) bt
#0  0x0000000000456790 in fm_status (qm=0x5eca60) at mem/f_malloc.c:515
#1  0x000000000041f172 in sig_usr (signo=Variable "signo" is not
available.
) at main.c:571

#5  0x000000000041f7f4 in main_loop () at main.c:925
#6  0x0000000000420446 in main (argc=Variable "argc" is not available.
) at main.c:1477


I do not know why this happened, but the system consists of to servers;
both running an dispatcher and a sip router (and a sql cluster node)
And both servers went bananas.

Any clues?
