I'm running Spamassassin 3.0.4 on a Dell Poweredge 750 with 2.8 Ghx CPU

5000-6000 users.
Everything is running great w/ the exception that the memory seems to keep
growing. On boot-up it seems to startup around ~500Mb and stay there for a
bit but then slowly starts to creep up and never looks back. In about 24
hours it grows almost to the full 2Gb. Right now it's at 1.8.
Should I be concerned?
erm.. Read those numbers cloesly.. 1.125 gigs of cache...
Ideally your physical memory usage should always be 100% (ie: memfree = 0).
That which isn't being used by programs should be used as disk cache until
a process needs more ram in which case the disk cache shrinks.
Instead of looking at your memfree, take a look at memfree + buffers+ cached.
Also keep an eye on your swapfree. And it is ok for a small amount of swap
to be used.. A good OS will realize that some pages in a processes memory
haven't been accessed for days and will swap it out to make room for more
disk cache. (It's quite typical for programs to have memory that's only
used when they start up due to lazy programing).
