RE: Memory usage very high

[Rick Carroll]

LINUX uses up memory for buffers and cache, but will release that memory for programs if needed.   What do free and/or vmstat tell you?   Remember, the values in the -/+ buffers/cache: can be available.   In my experience, you are only low on memory if you are actually seeing swap usage…                total       used       free     shared    buffers     cached Mem:       1030504    1002768      27736          0      31344     510704 -/+ buffers/cache:     460720     569784 Swap:      1044184          0    1044184   As you can see, I have a gig, and all of it except 27 meg is “used”. But I’m using 500+ megs for buffers and cache.     Rick     -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Thursday, March 20, 2003 9:06 AM To: [EMAIL PROTECTED] Subject: Memory usage very high   Hi there On our Linux Server (OS RedHat 7.3) memory usage is increasing up to 440MB (available RAM capacity 512MB). Usually it should not be any higher than 50MB. We checked all running processes and could not find a process using extremely much memory. As well a reboot has not helped to bring the memory down.   Does anyone know a solution???   cheers,   nadine
