[Freeswitch-users] freeswitch stuck at Push codec L16:100

[אריה קלטר]

Hello group

I have problem with one of our servers, that sometimes it starting to
stuck, on all new calls the last log line is "push codec L16:100" and
nothing helps to end the call, no response to bye from the calling server,
no response to sip info and even no response to hupall, the only thing that
solves the problem is restart the freeswitch itself.
It happened two times.
Any idea what is going on?

Example from one of the calls?

and the next line is

because i did hupall, but the call is still there until restart of the
freeswitch itself, even after the hupall.
