Since update 1.33.16~20200109103850-xenial

Hi,
Since today's update I am having trouble with recordings, here is what I see in the logs:

n 9 11:57:44 zm3 zma_m107[24040]: ERR [zma_m107] [Can't insert event: Lock wait timeout exceeded; try restarting transaction. sql was (INSERT INTO Events ( MonitorId, StorageId, Name, StartTime, Width, Height, Cause, Notes, StateId, Orientation, Videoed, DefaultVideo, SaveJPEGs, Scheme ) VALUES ( 107, 0, 'New Event', from_unixtime( 1578589010 ), 1920, 1080, 'motion detection', 'motion detection: none', 1, 1, 0, '', 0, 'Medium' ))]


System has become extremely slow.

Also, the cameras configured to record via a trigger don't record anymore:

I don't think anything of any significance has changed lately. What was your previous version?

That error means that something is holding a lock on the events table. You might just have to restart zoneminder. By restart I may mean stop it, check to see if any zm processes are still running, kill -9 them, etc...
