PJSIP Shutting transport

Hello, I have a situation.

Some times my asterisk server stoped response a SIP and after this all endpoints dropped

in console I received
res_pjsip/pjsip_transport_management.c: Shutting down transport 'TCP

So when this happens I need restart asterisk and all returns to work

That message occurs if a TCP or TLS SIP connection is established but no SIP traffic flows over it. Is this the case?

Thank you for answer

i dont use tls in case. I receive this message and all connections sip stoped including udp

As I said, it applies to both TCP and TLS. If the message has come up then something connected and sent nothing. What version of Asterisk?

My version is Version 17.0.0

Then I’d suggest determining what exactly has connected. If you do a wireshark capture do you see the traffic that you believe Asterisk is not seeing and processing? Are there any other messages? What does a deadlock backtrace look like[1]?

In next stop I will to capture traffic with wireshark and up asterisk with backtrace.
