[OpenSIPS-Users] What could cause a "terminating due to SIGCHLD"?

[Rodrigo Pimenta Carvalho]

Hi.


After letting OpenSIPS run 15 hours, there was a problem.

The unique messages that OpenSIPS was receiving were SIP REGISTER.

See the log:

What could cause this kid of issue? I just need some examples of cases to know what to investigate here.

Any hint will be very helpful!

Best regards.
