Description of problem:
The amount of memory used for pagetables constantly increases, until
the system starts swapping. Eventually the OOM killer gets rid of
processes, but the amount used never goes down significantly. I
checked the amount frequently during shutdown with SysRq-M, and it was
stuck around 210000 pages on a 1GB athlon64.
This seems to indicate that the leak is not due to a user space program.
Version-Release number of selected component (if applicable):
kernel-2.6.9-1.640 and kernel-2.6.9-1.643
Steps to Reproduce:
2. Wait a day or two
3. Listen to hard drive constantly seeking and watch machine become
Is your problem Bug #132947? Try the patch there.
I think this is a dupe yes, sorry. I haven't yet tried the patch,
since a rebuild of the kernel rpm ends up saying:
gpg: no default secret key: secret key not available.
Once I figure out how to get around that, I'll try the patch.
