[Freeswitch-users] FreeSWITCH 100% CPU utilization

Sun Apr 9 04:44:39 MSD 2017

Not sure what you mean by "not getting attached", but I ran strace a second
time (same parameters as the first) which locked up the server. Roughly 60
seconds later it un-locked itself and FreeSWITCH was starting up. No
problem since.

The only DB being used is Redis for call treatment upon call setup (some
calls require special DTMF handling), otherwise it's just vanilla
FreeSWITCH with an XML directory.

Regards,
Örn

Sure it's not getting attached? Or your DB?
