Title: Memory
Post by: simpleone on July 26, 2002, 06:04:54 AM

Hi all,

I seem to be having a problem with my e-smith 5.5 server in that it is using about 95% memory. If i stop and stop httpd, the memory goes back to about 60% but then straight back up to around 95% yet the swap space is not being used at all.

Anyone help with this ?

I too have exactly the same symtoms, below is the output from "free -t"

                                total         used        free     shared    buffers     cached
Mem:                       130648     125580     5068    0           30552      19904
-/+ buffers/cache:      75124       55524
Swap:                      265032      0             265032
Total:                       395680     125580     270100

128Mb RAM installed.. looks like 125 Mb being used..
But see the second value in the buffers/cache row..
thats what is actually being used.. (55.5 Mb)

running "top" and then enternig a capital M will show you what is using the most memory.

In my case its also HTTPD
Again for my system thats normal.

Hope that helps..
Andy

I don't think this is normal.  When I had 5.1.2 my memory was at 38% and with 5.5 it's at 95% it must be 5.5 that has this problem.
It is really slowing down my system when I have to make changes through server manager.  I am thinking of going back to 5.1.2.
Just my two cents.

Cheers,
Jehu.

This is not necessarily a problem, and the reason the server manager is slower is unrelated (it more likely relates to the forms-magic they're using for the multi-language support).
