Hi Slava,
There were some fixes in the auto-scaling in the last weeks, could you
confirm or not your issue against the latest 3.0 code ?

Hello Bogdan,
Upscaling error is didn't show up any more in logs at least I didn't
so it. Might need trigger bigger load.
*do you do auto-scaling only for TCP ?*
Our setup in most multi homed, as example public side TCP private
side UDP
*Now, about the TCP downscaling - I guess you see as terminated by
OpenSIPS the TCP conns anchored in the process that is terminated ?*
Yes, that how is look like end result that opensips start blocking TCP
connections. If specific process handle sip registration via tcp and
opensips trying close to down scale end point need send re register in
order do not loose registration. Other wise it cause stale
connections. Just close properly connection not enough I think.

Slava,
What about the upscaling error you originally reported ? is there any
way to reproduce it ? do you do auto-scaling only for TCP (no UDP,timer) ?
Now, about the TCP downscaling - I guess you see as terminated by
OpenSIPS the TCP conns anchored in the process that is terminated ? Is
is a proper close of the connection ? or ?

Hello Bogdan,
After we doing more testing with auto scaling we observed issue
with TCP, where opensips try scale down the processes it tear down
them and break TCP connections with end points and that cause
blocked connection state where opensips stops process TCP connections.

Slava,
Have you pulled my change on the improved log (just update from
master) ? and post here the new output you get for the error.

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,
