We're using this patch on two Linux servers of a four machine cluster running 3.0.1. We don't have memory or swap problems, but the patch appears to have eliminated a problem we'd been encountering since upgrading to 3.0.0: a few times a day each machine would have all its children die around the same time and become unresponsive for long enough that some messages (enough to generate complaints, I don't have numbers) would pass through unscanned. Each machine in our cluster currently handles on average 20 messages per minute with peaks around 60. With 1 GB of memory in each server, we aren't touching swap even though we're using the same machines to do ClamAV and j-chkmail miltering for most of the campus. -- Dawn Keenan Information Systems and Technology University of Waterloo, Waterloo ON
