Subject: [OpenSIPS-Users] WARNING:core:send2child: no free tcp receiver


Hi All
I am getting a lot of WARNING:core:send2child: no free tcp receiver,
connection passed to the leastbusy one (7)

I tried setting children to 20 that did not help, these warning start
being displayed right after I start openser. Users frequently get
service unavailable errors randomly when they try to connect, but I dont
know if this is related to this warning message or not.
 
As for the server there is plenty of CPU and RAM left, users range from
140 to 250 online all using tls. As for server limits 
 
I have set them to the following :
 
You have new mail in /var/spool/mail/root
[root at sero openser]# ulimit -a
core file size          (blocks, -c) 0
data seg size           (kbytes, -d) unlimited

pending signals                 (-i) 1024

POSIX message queues     (bytes, -q) 819200
stack size              (kbytes, -s) 10240

virtual memory          (kbytes, -v) unlimited
file locks                      (-x) unlimited

Is this warning message related to the serice unavailable problem, what
does the warning message mean in more depth and how to get rid of it ?
 
Thanks
 
 
 
Getting alot of
