My guess would be the nightly maintenance routines but can't say for certain. I'm sure someone else on the list can chime in.

Culprit was Message Tracking enabled without "Remove files older than (days)". We set the # days to 60, yet found that no log files were not removed, so I removed them manually. - What actually removes the log files once the # of days is met? Is it a service? - Should I remove all logs older than 60 days?
