tmpfs is 128MB. Most of the time only 1MB or less is in use. Perhaps I
should make it smaller?

This is typical output from free -m
             total       used       free     shared    buffers   cached
Mem:          1004        793        210          0         86     194
-/+ buffers/cache:        513        491
Swap:         1023        149        874

During problem periods, used memory will go from 513 to 800-900 and used
swap will climb to 400-500. 

I typically have 50-100 sendmail processes that are accepting mail and
are in the "cmd read" state. This does seem high to me, especially since
mimdefang is only processing a few messages per second.

Thanks for your help.
