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

[CARTWRIGHT, CORY C]

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:
