[Mimedefang] Getting "Error from multiplexor: ERR No response from slave"

[Cormack, Ken]

Group,

I am looking to see if I can replicate the content-filtering functionality
of eManager, which we currently use on our internal Exchange servers, via
custom SpamAssassin rules.

Porting the "forbidden strings" from eManager into SA "rawbody" rules, I
have thus added 7100 new rules to SpamAssassin.  Having SUCH a HUGE number
of rules, I am now seeing the following in my logs (where I had never
previously seen such errors before), and would like to ask the group if this
looks like some sort of timeout (due to extra time needed to process so many
rules), and which timeout values might be re-tuned to compensate.  Or am I
just insane for thinking SA can handle that number of rules.

Here's the error I'm seeing...

Thanks, in advance, for any feedback.
