Hello. I noticed a couple of recurring errors in the OTRS log: The first is as follows: Can't create PID GenericAgent, because it's already running As far as I understand, this means that two GenericAgent processes try to run concurrently. My crontab contains these lines created by default: */10 * * * * C:/OTRS/StrawberryPerl/perl/bin/perl.exe C:/OTRS/OTRS/bin/GenericAgent.pl -c db */20 * * * * C:/OTRS/StrawberryPerl/perl/bin/perl.exe C:/OTRS/OTRS/bin/GenericAgent.pl I have only one GenericAgent job that runs at 23:00 every Saturday. If I change the crontab as below, will it help? */10 * * * * C:/OTRS/StrawberryPerl/perl/bin/perl.exe C:/OTRS/OTRS/bin/GenericAgent.pl -c db * 23 * * sat C:/OTRS/StrawberryPerl/perl/bin/perl.exe C:/OTRS/OTRS/bin/GenericAgent.pl But what if I'll need in future more GenericAgent jobs that will run, say, hourly? And what is GenericAgent.pl -c db for? Second error is File 'D:/OTRS/OTRS/var/tmp/upload_cache/*********.ContentID.ContentType' doesn't exists! How come this happened and how can I fix this? Thank you. Ilya.
