<tt>Hi Slava,<br>
<br>
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 ?<br>
<br>
Also I just pushed a small commit to improve the date
provided by the bug log.<br>
<br>
In regards to the "not clear how to calculate"...could you
be specific ?<br>
<br>
Best regards,<br>
</tt>
