(gdb) print dest
$1 = (void **) 0x0

Now that you mentioned, I went to the log file and saw lots of this:

Apr  3 05:25:19 centos53_02005 /usr/local/sbin/opensips[29732]:
ERROR:tm:relay_reply: no more share memory
Apr  3 05:25:19 centos53_02005 /usr/local/sbin/opensips[29732]:
ERROR:tm:_reply_light: failed to allocate shmem buffer

(sorry, I should have looked into this as first thing)

I was load testing r.  6605 with 800 Registrations per second (32000 users)
and didn't saw this ever happen before (I ran this same load session several
times: one of them reached 1 billion registration requests). And actually,
in previous tests I was using opensips with just 256 MB of shared memory and
not with "-m 1024" as above.
With r. 6758 so far nothing wrong happened.
I will update to 1.6 head and will report if problem happens again, but
maybe in the above case, my SIPp instance went crazy in the other end and
generated too much traffic.

Thanks and regards,
takeshi
