I would check ksr_request_route() first if it contains any blocking operations like http_client or long database queries before sending a response to the sender

Hi,

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?
