Memory leaks?

hotplainrice · 2005-09-19 22:26:56

I've been monitoring my machine, its been up for 5 days. and its memory usage is always close to full. Fine, acceptable but whats rather odd is that swap usage has increased. I didnt run any additional programs compared to 2 days ago. 2 days ago, my swap usage was around 200000k used.

Now:
Mem: 502956k total, 495408k used, 7548k free, 10168k buffers
Swap: 666656k total, 549824k used, 116832k free, 80328k cached

Im running at the moment, Call of Duty: United Offensive server, firefox, opera, valknut, amsn and gnome.

Is this one of the signs of memory leaks?
How do I detect the culprit causing this memory leak?

Kill the big apps one at a time and monitor for a bit. See if you still notice the same thing.

Do you use the ck patchset? I remember reading somewhere about it doing something where swap was filled halfway to help with prefetching or something... that might be the problem?

hotplainrice · 2005-09-20 00:04:33

ck patchset nope, on pacmans scsi 2.6 kernel

ill try that phrakture.. thanks.

I killed valknut and noticed nothing.
Then i looked at top, and sorted apps by VIRT.

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
13560 hpr       15   0  424m 122m 2988 S  1.3 25.0  30:06.91 operamotifwrapp

13547 hpr       15   0 61812  27m 8008 S  0.3  5.6   7:28.53 opera

What should be the average VIRT size for operamotifwrapp?
Yea, I know thats the culprit.
Is it normal for X to eat up 252megs and Firefox with 106 megs?
Correct me if im seeing the numbers wrongly because me myself, I dont really understand VIRT, I assume its the storage on ram and swap added together.

It could be xorg. Sometime I check my system and xorg's memory usage increases after a while for no apparent reason.

phrakture · 2005-09-20 05:13:31

for the record, you should be able to ignore the virtual size, as that includes crap like shared libraries and files loaded. It's wierd....
For instance if procA is 5K, procB is 10K, and procC is 15K, and procA and procB both load the same shared library for an extra 5K, it's going to look like this:

       VIRT   RES  SHR
procA  10K     5K   5K
procB  15K    10K   5K
procC  15K    15K   0K

So, it's probably best to check out the resident size instead (RES)

Back on topic:
My X never even touches that much ram.... I can post my actual top output later...

Snowman · 2005-09-20 07:07:21

My X uses amount of RAM similar to
hotplainrice

PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
5374 root      15   0  213m  73m 3112 S  0.7  7.5  44:26.84 X

BTW, it's the xorg in testing. I don't use anything fancy. And as I said it is much lower just after X has started. :?

It only took the killing of opera!
Thats it.
So do I post a bug?

To Opera? Sure. The Arch devs didn't make Opera... it's whats called an "upstream bug" - i.e. not-arch's-fault

hotplainrice · 2005-09-20 23:43:24

Installing opera 8.5 from source solved it.

Gullible Jones · 2005-09-21 01:51:53

From source? Uhh... Wouldn't that be illegal?

maybe someone should supply them with a PKGBUILD...
