[OpenSIPS-Devel] [opensips] TCP listeners occasionally get stuck and consume 100% CPU (#410)

[Bogdan Andrei IANCU]

Hi @kelnos , your backtrace points to the lock for protecting the write operations on a TCP connection. This means you have a connection with a very very slow (and possible blocking) writing. 
I would suggest to switch to async writing for TCP:
             http://www.opensips.org/Documentation/Script-CoreParameters-1-11#toc82
or to stay in blocking mode but to reduce the write timeout:

Regards,
Bogdan
