Hello, 

i have come by a very strange problem. 

The internal sofia-profile just stops responding after a few days on Port 5060. Restarting the profile does not help, but restarting freeswitch itself does. 

Strangely enough, the external profile ( on the same ip, but different port of course ) keeps working. No Problems there.

A few things i have checked while it was happening the last time:

- Profile watchdog is disabled

- netstat -tlupn shows that freeswitch is still listening on Port 5060

- There is nothing useful in the logs, especially no error/crit message

- I can see sip-traffic arriving on Port 5060 with tcpdump, but it is not answered

- turning on sofia loglevel all 9 does not show anything

- It is not one or two specific ip's that get blocked, but all traffic

I also checked the firewall / fail2ban, but no problem there either. After all, a restart of freeswitch solves the problem, with no changes to the firewall. 

It happens on pretty regular basis ( every one or two days ), but there is no time-pattern in between the occurrences.

Im using debian 10, with FreeSWITCH Version 1.10.3-release~64bit (-release 64bit).

Has anybody come across something similiar?

regards,
