hello
this is a bit low if you want to manage high traffic. Try with
children=16 and see how the results are.
Cheers,
Daniel
What are the number of children you have in
config?
fork=yes
children=4 Do you get any error messages in the syslog?
not getting any error message in /var/log/syslog
Thanks,
Ali

Hi,
I am performing SIP to SIP performance testing using Kamailio proxy
(UAC-Kamailio-UAC). After increasing the load to 300 calls/sec
Kamailio begins dropping UDP packets. (250 cps works fine). CPU
utilization and network bandwidth looks fine. I think the bottleneck
is the Linux UDP buffer size of the proxy server. Here is the proxy
server information:
kamailio autodetects and sets the buffer size to the maximum
allowed.
What are the number of children you have in config? Do you get any messages in the syslog?
Cheers,
Daniel
