memory and swap question RH8.0

SchoolITguy · 03-20-2003, 02:55 PM

I have noticed that on my server the longer it runs the more memory it uses up(month or two), it will soon start spilling over to the swap file. I have had to reboot my server a couple of times when I have been setting it up haven't had a problem with it. But now that I have it set up and running and I don't want to be restarting every month. Is it normal for linux to do that? What will happen when the swap gets used up. All I am running is a small jabber server so nothing to intense.

Thanks,
Kevin

Did you find out what process was chewing up all the memory? If you are running X then it will chew up a lot of memory. Do a 'top' command to see what processes is hogging all the memory.

Well ...

you could look at actual memory usage per
process ... start top, press Shift-M, so it sorts
by memory usage rather than CPU.

Also I'd assume that there's WAY more than
jabber running on it since RH's starts a whole
truckload of services up by default...

You could try to check top's output over a few
days, and look whether any process is starting
to use more memory every day...

Probably one of the programs you are running has a memory leak. You might want to check what programs are using more and more memory (using tools like "ps" or "top") over several days.
Restarting the offendig daemon periodically might solve your problem.

I will watch that, is it ok to just leave the top program running?

Tinkster · 03-20-2003, 08:13 PM

Sure is :)
Top itself causes little overhead, and if you run it
with

Code:

top -d 60

it won't do any harm to the cpu, either

Updating once a minute is tame enough
for any situation ;)

for me, when i use top, it tells me that i am using 839784K of mem. I have no clue how it could be using up that much. There are 6 listings of mozilla-bin and i am only using 1 session of mozilla at this time. There are 14 listings for kdeinit. CPU using stays at 0.0% but sometimes goes as high as 3.3%. Do i have a memory leak or is this normal? i read in another thread that this is normal for memory to be shown as "used" when it is really just ready and waiting. My swap space also shows that it is not used at all (0.0%).

kdeinit seems to be an offender, I have just started a new thread about this. I am searching the forums at the mo but can't find much info on how to deal with this.
