I keep getting these errors in our system log
OTRS-GenericAgent-10 Can't create PID GenericAgent, because it's already running (domain.com/15148)!

The domain was changed in the email and the number is different on each line of the log.


I was also wondering how to clear the system log. I have fixed most of them and need a clean log to see if they are coming up again.


Thank you
Dillon
