Hello,
We’ve been
running Kamailio 5.5.0 for a while now and recently ran into
an issue where the application buffer would get full and
Kamailio has a lot of difficulty keeping up with REG
requests. This severely impacted Kamailio’s ability to
perform and resulted in many REG timeouts.
Running ‘watch netstat -ulpn’
revealed the buffer issue.
We usually
run the production system at log level INFO (2) and had not
ran into any issues in the past.
When the
buffer issue occurred and after some testing, we discovered
that changing the log level to NOTICE (1) was sufficient to
bring the system back into operational status.
For example,
at log level INFO (2) we seem to achieve ~150-200 REG/s
while at log level NOTICE (1) we reach ~500-700 REG/s.
I did find
this article in the wiki and tried using the “-“ in front of
the log path but this didn’t seem to help.

Even writing
the logs directly to our external log server and preventing
them from being written to the local disk doesn’t seem to
alleviate the issue when the log level is set to INFO (2).
Does anyone
have any experience with this or have any suggestions? We
are finding it difficult to scale as a result of this issue.
Thank you in
advance.
Amit
