Hello,
I am using Kamailio as a SIP proxy.So it receives SIP packet from
internet and forwards it to FS servers in local network.When i execute
"ss" command i see very high value in RECV-Q column.I THINK IT IS NOT
NORMAL.PLEASE CORRECT ME IF I AM WRONG.

Initially i thought that there is something in script which must be
causing kamailio to process UDP request slower but i faced same issue
with a very simple script where i simply reply with stateless 200 OK
for each sip request :
request_route {
sl_send_reply("200","OK");exit;
$avp(uuid) = $rm + "-" + $ci;
........
.........
.........
.......
Server configuration :
OS : CENTOS 7
Kernel : 4.16
CPU : 5 X Intel(R) Xeon(R) CPU E5-2680 v2 @ 2.80GHz
RAM : 32 GB
Please help me debugging this issue.Thanks in advance
if you have performance issues just with a very simple config sending a
stateless sip reply, then check your system/firewall
configuration/limits. Specially on centos, I have seen a lot of
restrictive traffic rates limits set by selinux. Also, if you run in a
virtual machine, there can be limits enforced by the vm platform.
If you still cannot sort out, I would just run similar tests on a
vanilla debian.
Cheers,
Daniel
