Hello Bogdan,
My question how to calculate correctly
*tcp_workers*
*udp_workers*

to properly assign with in auto scaling profile. Which parameters
need use as base ?
As example if vm 4GB memory up what will be max number for scale up
processes and what should be value for tcp and udp workers.
It message is appear in log on first attempt to fork in scale up.

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,
