Daniel,

Here is the version information.

	root at tel-vc-fs03.telariscom.com> kamailio -v
	version: kamailio 4.1.2 (x86_64/linux) 73ea61
	flags: STATS: Off, USE_TCP, USE_TLS, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, DBG_QM_MALLOC, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES
	ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 4MB
	poll method support: poll, epoll_lt, epoll_et, sigio_rt, select.
	id: 73ea61 
	compiled on 20:41:21 Apr  1 2014 with gcc 4.4.7

We don’t see this happen in the lab environment.  It only happens in production so we are little concern about it failing.  Unfortunately, we don’t have any core dumps of this occurring; we didn’t have that feature enabled when this happened.  

By enabling “men_safety”, will this affect the processing of any of other signaling messages when an error occurs or will it only affect the transaction in which the error occurred.  There isn’t much detail in the description of this flag in the documentation to layout how it affects the overall system in an otherwise “abort” situation.  Your assistance is appreciated and I hope that it doesn’t sound like we are being difficult but this element is setting in front of our entire network and failure causes us to block all calls.  We were running close to 800 CPS through it when it failed.  We don’t see any load on the machine that would indicate that the issue isn’t software based.  If the “men_safety” will not affect the rest of the traffic, we can add this as well as enabling core dumps and try it again when we can closely monitor the system.  Please provide the additional details about “men_safety” so we can assess the situation.  Is there any other information that I can provide to assist your input like the part of the config file or what else?
