[Mimedefang] tmpfs on Linux

[Greg Miller]

Platform is RedHat EL AS 3
Dual Xeon 3.0 Ghz CPU
1 GB RAM
Load is between 1-3 messages per second.

System performs very well, most of the time, with only 2-3 busy slaves.
However, on occasion, I will see all 15 of my slaves busy, lots of disk
I/O to swap, and "Please try again later" messages in the maillog.

I am using tmpfs for /var/spool/MIMEDEFANG as recommended in the FAQ. I
believe my tmpfs is being sent to swap during these periods and causing
horrible performance.

Has anyone else seen this behavior? Any solutions out there?
Thanks.
