Double GenericAgent cron jobs

[gofster610]

The issue I'm having is this. There are two entries for the 20 minute GenericAgent run in the cron job. Here's the output from crontab -u otrs -l :

I've checked the files in /opt/otrs/var/cron/ and have the following files:

aaa_base
fetchmail
generic_agent
generic_agent-database
pending jobs
postmaster
postmaster_mailbox
rebuild_ticket_index
session
unlock

I've check the generic_agent and generic_agent-database files. The first one has the entry:

# --

# Copyright (C) 2001-2009 xxx, http://otrs.org/

The second one has the following:

So, the files look fine. I'm just not understanding how the cron job is getting the two entries for the same job. I've tried stopping and restarting the cron job using the ./Cron.sh stop otrs and ./Cron.sh restart otrs, and the second entry always shows up. Any ideas?

crontab -e edits the crontab.

[gofster610]

I've edited the crontab file to remove the duplicate entry. The issue is that if I restart the server or rebuild the crontab using ./Cron.sh restart otrs, then the duplicate entry comes back and I have to remove it once again.

I'm hoping to find a long term solution to the issue instead of a work around. Thanks for the input though

Have a look in all files in var/cron/ it seems that one is double from the content... (Perhaps a mistake during installation?)

[gofster610]

Ok,

I figured it out. When I edited the files in /opt/otrs/var/cron/ , a hidden backup file was also being created in the directory. So, I had generic-agent and generic-agent~ . When the crontab was re-created, it was using both the current file and the backup file causing me to have two different generic agents running.

So, that's pretty wacky, but I'm glad I got it resolved.
