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.
