MT Collector

We currently have the collector running. We also have a program document set to purge once a week in the early morning that won’t run to completion. What am I missing? When I run it from the console it works.

This is what the log shows:

Running Program document for ‘mtc purge 14’

Starting purge of old documents in log file

MT Collector: Started

MT Collector: Already running

MT Collector: Shutdown
