[OpenSIPS-Users] Opensips debug logging performance impact

[Govindaraj, Rajesh]

Hi,

To debug an issue related to udp send failed, opensips was run in debug level 5 in version 1.11.5.

We found that opensips performance went down. At a particular time, the thread were blocked for 3-4 seconds while trying to send tcp messages. On code browsing doesn't look like opensips is waiting for something and delay is purely happening because opensips thread was not scheduled.

We analysed for any increase in load for opensips around this time but could not find any significant increase in input load.

Just wanted co-members advise, does debug logging slow down opensips to such an extend where message processing delays are so much that keep alives fail and noticeable impact happens?

Please advise.

Thanks,
