With Kamailio 5.5.3 (with KEMI/Lua) I noticed it apparently had stopped responding to OPTIONS in my test system. It can cause problems if a similar issue appears in production.

Only thing i could observe it was apparently responding to INVITE and CANCEL etc randomly , its pretty strange as it was not dead completely. There was no core dump, I restarted and it started functioning again.

Any clues please?
