<p class="MsoNormal" style="margin-left:35.4pt"><span lang="EN-US" style="font-size:11.0pt">We are actually sending the logs directly to our local graylog server via the $programname property in rsyslog, and we’ve disabled writing Kamailio logs to disk (i.e.
only in memory by setting Storage=volatile in rsyslog.conf) but that didn’t seem to help with the application socket receive buffer backlog.<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-left:35.4pt"><span lang="EN-US" style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal" style="margin-left:35.4pt"><span lang="EN-US" style="font-size:11.0pt">Keep in mind that for testing purposes, I am blasting Kamailio with a fixed 2000 simultaneous registrations, so at log level 2 it really struggles and the socket buffer
quickly fills up. Reducing the log level to 1 allows Kamailio to rip through the requests and the buffer stays at 0.<o:p></o:p></span></p>
