Title: Disk swap at 0% constant
Post by: Darren on June 25, 2002, 01:48:39 PM

I use physysinfo to see how my server is running but i never see the disk swap above 0% and the memory runs at 90 to 98 % constant is there any reason for this.
Cheers Darren

It's a feature! You've paid for that RAM, after all. Linux will do its best to use
all the real memory available for something, whether allocated to programs
or for cache, and to keep things out of swap when possible.

You can check the accuracy of phpsysinfo at the command line with the
command "free", which will break things up a little further:

$ free
             total       used       free     shared    buffers     cached
Mem:        776640     623112     153528     644856     135284     356272
-/+ buffers/cache:     131556     645084
Swap:       265032       1144     263888

That's probably similar in proportion to what you're seeing -- 620MB of
776MB are in use, but 131MB of that is buffers and cache.

Cheers,

Hi there,

Are you using SquirrelMail v1.2.6 or v1.2.7 ???
Then switch back to v1.2.5, it has to do with a memory leack on the Red-Hat distributions and a few scripts of SquirrelMail who are bad in the new versions.

Greetings
