[OpenSIPS-Users] auto scaling

[Bogdan-Andrei Iancu]

Hi Slava,

Based on the OpenSIPS logs, did you get that error on the first forking 
attempt or sometime later after some number of new tcp processes forking 
? More or less, my question is : what was the process 
creation/termination history before getting that bug log ?

Also I just pushed a small commit to improve the date provided by the 
bug log.

In regards to the "not clear how to calculate"...could you be specific ?

Best regards,

Bogdan-Andrei Iancu
