The size you see there is a combination of things such as memory mapped to the video card, shared libraries, and actual physical memory. The mapped video memory, which can be huge depending on the dedicated memory on your video card, does not take up physical RAM. Most of it is just stored on the device itself, but for various reasons, need to be shown as part of memory. A 64M video card would add 64M to the total number, but would use almost no actual system RAM. There are also a bunch of shared libraries that contribute to the total. These include glibc and a bunch of other libraries. You can probably look somewhere in /proc to find the breakdown. In any case, the footprint of X minus shared libs is probably aroud 3-4M. Finally, the actual runtime memory likely depends on things like your choice of desktop background, bit depth, screen resolution, existence of some sort of buffer area for clean redraws, etc..

[expert] Memory Leak in XFree updates
Hi. Ever since I updated my XFree packages last week, I have been seeing X use massive amounts of memory and I am concerned there may be a memory leak or something. Here is some output from top.

Todd- Found out why it was doing it with an "open" window Seems to have been related to my problems with X. It seems that at times windows "appear" to be open but in fact the process controlling them has quietly died without error. Eventually the screen will refresh and the window will disappear. (usually when I come back to that "page" in my wm and try to do something with it.) I know I'm getting a lot of weird errors of late . thanks for being tolerant.

Todd i was able to do this with mcedit as well. sometimes after working with mcedit in a konsole, if i simply close the window without exiting mcedit, it keeps running in the background taking up to 90% of my cpu.. however it doesn't happen every time and i have to try several times to reproduce it.

I can reproduce this since RedHat version 6.2, but only in an error scenario. 1) ssh to a box. Any box, it doesn't matter.

I tend to use emacs a lot more, but vi and visudo are still very important to me. I have not had a problem with vi grabbing CPU ever. It is a nice lightweight editor with a neat way of keeping hands on keyboard. jabberd has given problems (eating available RAM) on every single box where I tried it and I tried it on all just to verify that it is most probably a memory leak.

All, In my continuing effort to solve other problems on my box I found something interesting. for the first time the box had started to slow down. Dramatically. So I checked the term window running top and sure enough a program that I had running in a tty window was now using 98% of my CPU.. The program ..

[expert] Memory leak?
I'm running 8.1. After starting my system, I've noted the amount of memory and swap space being used on a "top" display. After a reboot, there's always 0 swap being used. I've noticed that the longer the system runs, the more memory resources show up being used, and the bigger the used swap space gets. I came home from a trip recently to find my Linux box stopped for no apparent reason, and after a reboot, none of the system logs showed any errors at the point where the system stopped. I've pretty much got the same things running all the time. I'm beginning to think that *something* has a nasty memory leak, but I don't have a clue as to what. Is there a way to identify programs that have memory leaks? Something that can track the memory usage of program running in the system or whatever?

[expert] "Memory Leak"
I figured I should share this result from the crashtesters. One of our crashtesters installed Traktopel Beta 2 and was running compilation programs. And his memory was used up... his swap was hit hard... and the system informed him it was out of memory and shutting down bash. Reinstall--same technique, same symptom. Fortunately the crashtesters have scripts that phone home with configuration information. I spotted a WD and a Maxtor on IDE0 and recommended he separate them--one on ide1 and one on ide0. He did this. Another reinstall -- same technique NO symptom--been reunning well since that time. Timing chatter on the IDE bus Some DVD-ROMs on VIA chipsets can cause corruption of install-time data on hard disks past kernel 2.2.15. WD and Maxtor of same speed or a slower WD with a fast Maxtor master will just eat your data with timing chatter. And since WD doesn't do the CRCs necessary to check, you can actually boot and run on a corrupted system (for a little while, anyway). Civileme
