A lot of apache processes

[chemicstry]

Hello, recently i noticed that something uses a lot of ram so i sorted top by memmory usage and i saw that there are a lot of apache processes that each use about 200mb of ram. Killing the process doesnt help. I tried to google, but couldn't find anything similar. Hope someone helps me.

i'm not an apache expert, but you need to look at the RES column in order to see actual memory usage of a process

also, use free -m command to see actual free memory, -/+ buffers/cache line is what you want to look at

Thanks for reply. In "RES" section apache uses 13mb that doesnt hurt but something eats all my memmory. If i add everything from top it will be about 2-3gb but not 6gb.

EDIT:

debian:~# free -m
             total       used       free     shared    buffers     cached
Mem:          5986       5692        293          0        481       3409
-/+ buffers/cache:       1801       4185
Swap:        17539          0      17539

also, use free -m command to see actual free memory, -/+ buffers/cache line is what you want to look at

So i got 4gb free?

Well, technically* it's been assigned to buffers and cache to speed things up. But when it is needed for actual work it will be used - so it's available. I've never been able to make up my mind if that actually counts as free**

you have 1801 mb used, 4185 of physical memory free for applications to access (and do clarify for roky, that would be once the buffers and cache are freed if necessary)

normal memory usage. Not abnormal.
