Hello, since we've done the update from 2.0.4 to 2.3.1 (spent some days testing 2.2.7 before applying the patches for 2.3.1), we're have massive problems with the number of database-connections. Our MySQL database (5.0.51) runs on a different server, with the customer user data stored in a separate table within the otrs database. Almost every day the connections reach our max_connections setting, which had to be changed from 30 (back when we used 2.0.4) to the current value of 400 connections. 'Show processlist' on our db server show numerous (almost always >150) processes with times >20000 seconds, all sleeping. Currently it looks like the only time connections are closed is when we're doing an otrs/apache restart (it's basically the apache restart, but restarting otrs as well is generally quicker than waiting for the scheduler...). We have only about 10 agents on the system, SessionMaxTime is currently set to 16*60*60 (16 hours) which has been working absolutely fine for the last 2 years... The installation runs on SLES 9 using Apache 2, MySQL is installed on SLES 10, there are more dbs on the server, but only the otrs connections pile up. I just changed the session timeout to 8h to see if this helps - but since it had been working with the old version, I'd rather stick with 16h. Any other suggestions where to look?
