Debian - Can't create PID PostMasterMailbox [SOLVED]

[msignorello]

Hello,

I have been struggling with this issue for the last day or so. I am installing on Debian 7, from source. I have a separate MySQL database server.

The packages provided by debian worked 100%, but in this installation - I need to install from source as the Debian Installer crashes when you select to not provision the database at install time. Since I am using an external DB source is easier.

That said - I can manually check accounts with the pop3 connector all day long through the admin interface.... no errors

When I have the CRON jobs enabled i get one check of messages, and then every subsequent check fails with the: Can't create PID PostMasterMailbox, because it's already running

I have already changed the postmaster ID, as well as message size with no change.

I even went as far as deleted the DB and install folder, and re-installed with the same result. I am convinced I am missing something here, but not sure what.

Can anyone assist?

Thanks!

Matt

Upon comparing a debian install script to my own configuration... the OTRS user was not a member of the www-data group.

This prevented the temp files from properly being created and therefore would not remove the SQL tracking instance when fetching mails.
