Memory on Apache

clefeitosa — Fri, 03 Aug 2007 08:55:42 GMT

Hello guys,

I'm using B11.11 with 4GB of memory and we have an apache running on this server.

This server is always using only 2GB of memory and i don't know why...

Is some configuration in the apache (http.conf or something else) that limit the use of memory?

How can I see why the server is using only 2GB of memory:

SAM -> Performance Monitors -> System Properties:

Physical Memory: 4097.7 MB ││ │
││ ││Real Memory: ││ │
││ ││ Active: 224348.5 KB ││ │

││ ││Swap Space: ││ │
││ ││ Avail: 12288 MB ││ │
││ ││ Used: 453 MB

Please, could someone give me a help?

Thanks!

And...? You expect Apache to be using more? If Apache needs additional RAM, it will take advantage of it. I don't see what the problem is.

is there any performance issue using 2GB RAM?

When you do a swapinfo, please use -mat.

(We don't know what no stinkin Kb is and all of those zeroes blind us. :-)
