True, I don't have much on troubleshooting in the MAQ page... sorry.

Your system seems to be struggling...

The debug should give you some output while restarting mailscanner.

What kind of performance stats do you have?  What top says?

Cpu usage?  Load average?

what is the output of "free"?

what is the output of "vmstat 2"  (let it run for 5-10 lines, then ctrl-c).

Are you sure you don't have a disk that failed in one of your RAID
arrays or something?

So you've modified the default setting?  If it says it is sanning 90
messages, this is usually a good sign.
