Memory Usage {Scanned}

[Karl Bailey]

I've run MailScanner with sendmail for over a year, hasn't gone wrong once, I always upgrade to latest version. Mail gets past through spam assassin & three virus scanners, it started life on a 2Ghz dual xeon machine with 1 Gbyte ram running RH7.3, it now lives on a 3Ghz dual xeon with 2Gbytes ram under RH9.0. I also manage a remote mailscanner in a small office RH8.0 single 1100Mhz PIII with 512MBytes ram.. Same results! The machines are dedicated & no gui is running, it's a very trimmed down install.

My memory usage is through the roof all the time, never drops below 90% of physical memory used, this was first seen using snmp, I got interested & ran mailscanner-mrtg both show the same thing.. Memory usage through the roof. I can attach the mem graph if you wish.. But my point is... There seems to be no problem with this machines are solid, but I am interested in why the memory usage is so high, I figured I'd claw some of the memory back when upgrading the machine to 2Gbyte of ram but it seems as much of the memory is grabbed as possible by MailScanner.

I thought the same thing, but Ricks comment are correct.

Here is my output. Look at the 2nd line under free. I have 781256 free.
