Hello,

Thank you for your reply 


I follow your suggestions to modify SHM_MEMORY ,PKG_MEMORY value and the system only two uac register. 

See the program after I start kamailio.



shm memory 1G  

pkg memory 10M



sh-3.00# ps -ef | grep kamailio
root     23627     1  0 12:57 ?        00:00:00 /home/pkg/kamailio-3.3.4/sbin/kamailio -f /home/pkg/kamailio-3.3.4/etc/kamailio/kamailio.cfg -P /var/run/kamailio/kamailio.pid -m 1024 -M 10 -u root -g kamailio
root     23635 23627  0 12:57 ?        00:00:03 /home/pkg/kamailio-3.3.4/sbin/kamailio -f /home/pkg/kamailio-3.3.4/etc/kamailio/kamailio.cfg -P /var/run/kamailio/kamailio.pid -m 1024 -M 10 -u root -g kamailio


This problem is still the same last crazy the sending options message for uac
But the /var/log/syslog not the same as follows 

Mar 20 12:58:53 cfa /home/pkg/kamailio-3.3.4/sbin/kamailio[23637]: CRITICAL: dialog [dlg_timer.c:205]: Trying to update a bogus dlg tl=0x77052ae4 tl->next=(nil) tl->prev=(nil)

Hi,
I had this "issue" some times ago. It turned out that I needed to increase the value of SHM_MEMORY, since by mistake I forgot a 0 on the value (1024 vs. 10240). However this happened only when high loads on system.
I needed also to tune PKG_MEMORY to my needs. ( both on /etc/default/kamailio )

Check your settings and see if this helps.

Br, Rinor
