I'm not sure if I'm having the same issue, but I am experiencing some
severe memory issues. After a reboot, free -m looks like this:
[EMAIL PROTECTED]:~$ free -m
total used free shared buffers cached
Mem: 3033 724 2309 0 29 406
-/+ buffers/cache: 288 2745
Swap: 3773 0 3773
As you can see, I have 3GB of memory, and I'm using less than 300MB. No
big deal. However, over the course of a week, the +/- buffers/cache
line slowly increases to nearly 3GB. Running top and hitting shift + M
does not show any processes hogging memory. In fact, the list looks
almost identical to what it looks like immediately after a reboot. No
more than 150 processes, and none are using higher than normal amounts
of memory. And even if I shut down -everything- on my box, including
GDM, X server, etc, and login to the console on CTRL-ALT-F2, my memory
usage does not decrease at all.
I'm -guessing- this is some sort of kernel level driver leak with the
nvidia driver, based on what I've read from others. But I do not know
how to confirm this. Is there a way to get the kernel to print a
mapping of it's internal address space to determine what's using this
memory? Or does anyone have any other suggestions as to what to try?
I'm running Ubuntu 7.10, without Compiz (I completely uninstalled it)
