Topic: HELP!

[Tyrone Miles]

I am having a memory problem on my server, my server is slowly eatting up all my ram. Right now I have 512 MB in my server and right now it's running at 78% of total.

I went to the command prompt and put in ps aux and noticed that I am running like 21 instances of httpd??? Is that normal. (Each is taking 2.2% of my ram)

My server used to have 256 and it was runnin at like 98% then so I put in more and now it's creeping up again. (Over the last 4 days)

Help?

As far as I can remember, Linux will use as much ram as you can give it.  I have 22 instances of httpd running on my server with only 128Meg ram.  So, that many instances of httpd sounds normal to me.

That is cool, I just don't want to start using swap space that will slow my server down.

Try to look at your server loading by the Server-manager addon, for my server, I found most of the usage are for buffer and will release after a while.

Thanks to Shad Lords's work

you will then see the loading will even go up to 90% (in mycase 192M ram) but will then fall to 61% after a few hours after mid-night......

To feel safe, the best way is to monitor it with your own eye.  Trust the system, it is not a M$ box..... who need more that 512M to run.......  for Linux, 512M Ram is not just big, it sounds like a XXL size to me !! (Where I thing my 192M ram is just M size)        (:-p)

I have that running. Now my memory is running at 85% of total. I am getting worried. Let me look at the trends in Sysmon. Thanks for the help.

My home server, PII w/192 megs RAM (was 128, but I threw in 64 more for just this experiment) pretty much always is at 85-98% RAM usage.  I've never seen it get into swap space, though, and it's fairly heavily customized and gets lots of use, from caching DNS server to the home LAN to outside hits for Gallery and Zoë.

Just my 2¢ ...

Oh yeah, I almost forgot the biggest use ... NETJUKE!

Perfectly normal, read the linux FAQ. What's abnormal is operating systems which *don't* make use of the RAM which their owners have provided (sometimes at great expense) for it to use. Go figure.

That is cool, I am just worried about it going to the max then having to use swap space. I notice when my machine uses swap space my performance goes down
