Memory leak in ocfs2/dlm?
...a 2.6.19-rc6
on a x86_64 box, 4GB RAM.
A simple `ls -Rn' on a filesystem with lots of files makes the box
leak so much RAM that the OOM killer starts to kick in. With slab
alloc debugging turned on, we see this:
# mount; ls -Rn; wait some seconds; Ctrl-C
[root@lnxp-1038:/backend1]$ cat /proc/slab_allocators | egrep '(size.512|ocfs2_inode_cache)' | grep ocfs | sort -k 2 -n

It is not ubuf leak which is addressed in this thread. Good news.
