[SR-Users] Kamailio stops processing requests over UDP

[Juha Heinanen]

I'm returning to an old issue, where Kamailio stops processing incoming
requests.

Now it turned out that only requests over UDP are not processed.
Requests over TCP work fine.  Debug log doesn't show anything about the
requests over UDP, but wireshark sees them coming.  core.ps shows that
main process - attendant and all udp receiver processes are alive.

Any ideas what could cause Kamailio (5.2 version) to stop processing
requests over UDP?  What additional info should I try to get?
