[OpenSIPS-Users] cluster presence

Sun Jul 1 00:28:03 EDT 2018

Hello Bogdan,
I checked database connection and it looks normal ping less then sec to 
database.
I monitored load on database nodes and didn't notcied any extra load on 
them.
Right now I see 2 types of messages on all cluster nodes.

Jun 30 22:56:45 aitossbc01 /usr/sbin/opensips[20245]: 
WARNING:core:timer_ticker: timer task <presence-dbupdate> already 
scheduled 100410 ms ago (now 700510 ms), skipping execution
Jun 30 22:56:45 aitossbc01 /usr/sbin/opensips[20245]: 
WARNING:core:timer_ticker: timer task <presence-pclean> already 
scheduled 191700 ms ago (now 700510 ms), delaying execution

and

Jun 30 23:14:36 aitossbc02 /usr/sbin/opensips[9376]: 
WARNING:core:utimer_ticker: utimer task <tm-utimer> already scheduled
