Hello, I have setup the latest otrs (3.0.9) recently. It works fine except for one thing. Everyday at the same time otrs hangs for several minutes. This are the things I see at that time: - the otrs web interface is not responsive. - the load skyrockets - restarting apache doesn't help After some time (about 10 minutes, I think) the system stabilizes and everything works again. It looks to me the cronjobs are triggering it. However I don't understand why it only is at that time. And not every hour. Please note, I'm running the postmaster mailbox cron every 5 minutes. Please see the attachment. I also get this error: ERROR: OTRS-otrs.GenericAgent.pl-10 Perl: 5.10.1 OS: linux Time: Fri Jul 22 09:40:13 2011 Message: Can't remove shm for log: Invalid argument Traceback (1222): Module: Kernel::System::Log::CleanUp (v1.64) Line: 250 Module: Kernel::System::Log::new (v1.64) Line: 101 Module: /opt/otrs/bin/otrs.GenericAgent.pl (v1.4) Line: 79 Identifier removed at /opt/otrs-3.0.9/Kernel/System/Log.pm line 226. How can I further debug this? Thanks in advance, Rudy!
