Dear,

Every 10mn we receive a mail with object and body as below.

Object : OTRS Scheduler Daemon Cron: MailAccountFetch

Body:

Error: Unable to register the process in the database. Is another instance still running?

You can use --force-pid to override this check.

How to fix that?                 

OTRS-ITSM 5.0.6

Regards,

Placide
