[OpenSIPS-Users] Possible bug: CRITICAL:core:internal_fork: #012>>> no free process slot found while trying to fork again#012

[CARTWRIGHT, CORY C]

Hello Bogdan,

Sorry for the delayed response, I was on vacation last week.  I am unable to duplicate this in the lab, so I'm leaning towards the option to not crash when the error occurs.  I will also respond on github.

Thank you,
Cory

Hello,

Ran across this in my syslogs, so far I have not been able to determine if it's actually affecting calls as our service is not based on live calls.  Here is the full message:
