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@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

Probably the proxy tries to open new tcp connections. This will fail after some timeout. During waiting for the timeout the TCP processes are busy, thus they can not handle new requests (as the warning says)

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@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

The TCP timeout is usually some seconds. Thus, during this time the TCP process is blocked completely.
I described this a few weeks ago very detailed on the list - please read this thread: http://lists.kamailio.org/pipermail/users/2008-December/020845.html

Probably the proxy tries to open new tcp connections. This will fail after some timeout. During waiting for the timeout the TCP processes are busy, thus they can not handle new requests (as the warning says)

Hi Ali,
An easy way to reduce the IO waiting time is to reduce the timeouts for TCP: 1) timeout for setting up a new tcp connection - tcp_connect_timeout: http://www.opensips.org/index.php?n=Resources.DocsCoreFcn#toc68 default 10 seconds, set it to 2 secs
2) timeout for sending a package - tcp_send_timeout: http://www.opensips.org/index.php?n=Resources.DocsCoreFcn#toc67 default 10 secs, set it to 2
Also, do you have clients behind NATs?
Regards, Bogdan

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@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
