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
file size (blocks, -f) unlimited
pending signals (-i) 1024
max locked memory (kbytes, -l) 32
max memory size (kbytes, -m) unlimited
open files (-n) 101024
pipe size (512 bytes, -p) 8
POSIX message queues (bytes, -q) 819200
stack size (kbytes, -s) 10240
cpu time (seconds, -t) unlimited
max user processes (-u) 16382
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
