People are using Kamailio with a lot of logging in high load situation usually without problems, there has not been a lot of reports about that in the past. Maybe it something related to a specific distribution version? I checked, the rsyslog is using asynchronous writing as default since a long time. What logging engine do you use?

I was logging to a local rsyslog and rsyslog was just writing to a file on a local ssd (unsynced). It's a ton of log. But meh. I disabled syslog entirely and enabled log_stderror = yes Then I just captured stdout+stderr via multilog and write it to a file on the disk. The problem went away. I think there is some huge overhead in the way kam packages up the log and sends it out to syslog. -- Jeremy Kister https://jeremy.kister.net./ __________________________________________________________ Kamailio - Users Mailing List - Non Commercial Discussions * sr-users(a)lists.kamailio.org Important: keep the mailing list in the recipients, do not reply only to the sender!
