Jens, do you still get this?
No, current uptime is 31 days and top reports: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 3789 root 15 0 9982m 879m 10m S 0 12.5 58:43.67 Xorg Nevertheless it was in the past reproducable. What changed? Two things: * I applied security updates * I updated Xen from 3.0 to 3.2 $ rpm -q xorg-x11-server xorg-x11-driver-video xorg-x11-server-7.2-30.13 (old version was 30.8) xorg-x11-driver-video-7.2-33 (not changed) $ uname -a Linux imkf-pc073 2.6.18.8-xen #1 SMP Fri Jan 25 09:16:47 CET 2008 x86_64 x86_64 x86_64 GNU/Linux
I don't think it is the driver (especially not the nv driver as drivers usually don't allocate anything at runtime).
OK, it was just a wild guess. But please tell me (and all other person who find this bug later on) what could be the reason? Is the X.org server the only possible reason? Why are others not affected? What diagnostic to you prefer additionally for the next time?

In most other cases it can be attributed to clients allocating pixmaps on the server which they don't release. Some huge numbers also result from mapped memory which is either framebuffer or some memory address space. But you said that memory consumption in was increasing in your case. This is certainly a scenario which we don't see reported too often. The only to debug this I can presently think of would be a memory debugger. The server itself doesn't contain such a thing any more so you would have to resort to whatever is in glibc or some other tool library you can preload. This will however require that you terminate your server - and after a restart things may be quite different already. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I have no idea why this was getting so out of hand in your case.
Heh, I think I found it! Whenever I start and exit a special Motif application (non free) the memory increases by approximately 10MB. I did it 100 times in a loop and got: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 3789 root 15 0 11.9g 2.0g 10m S 0 28.6 61:06.52 Xorg The 2 GB values doubled it's size from initial 0.8GB! But it is still an Xorg bug as the memory should be freed once the applications ends, right? The program itself initializes menus, allocates a few strings (probably without freeing with XmStringFree), a larger pixmap and initializes OpenGL (Mesa-6.5.1-23) without using it much in my case.
In most other cases it can be attributed to clients allocating pixmaps on the server which they don't release.
Shouldn't xrestop show this? Are there other tools?
The only to debug this I can presently think of would be a memory debugger.
Such as valgrind :-)) OK, now it is at least reproducable for me. There should exist also a few faster memory checkers.
This will however require that you terminate your server.
That's no problem for me. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
