Is there any way to manually clear incoming connections?

I have been running SF for about a year-and-a-half, and it works well.  But for the last week I have been having a problem with incoming e-mail connections being held open for excessive periods - in excess of 1 hour.  I recall seeing this once before, several months ago.

Saturday night, a customer called me to ask if we were having a problem with e-mail, because he had not received any messages.  I checked SF and found that it had 100 connections open.  When I checked the logs, I found that it had been rejecting new connections since 5:45 p.m. on Friday.  My monitor didn't catch the problem since the server was reachable, and would accept an incoming connection, but immediately close the connection.

The only solution I could find was to restart the service.  I am still seeing as many as 65 "stalled" connections - usually between 1 and 2 hours old, sometimes longer.  They all report Status as "QUEUEING EMAIL".  If I let SF continue to run, the messages will evenutally clear, but will be replaced by more stalled messages.

I am running two instances of SF on the machine, one as a service, the other in standalone mode.  Only the one running as a service exhibits the problems, I presume because of the domains handled by that server.  All stalled messages appear to be junk - all either have no recipient address or a bogus address; about half have no Sender address, the rest are "spammy" addresses.

Any help would be greatly appreciated.

The new SpamFilter v2.7 does a much better job of handling stale connections, and has a new, real-time connections tab showing the current connections (the older versions were not displaying real-time data).
Both the new v2.1 and the new 2.7 allow you to click on the "X" column for a connection to manually terminate it, but again, this process has improved in v2.7.
