I answered this in jfs-discussion, but for curious on linux-kernel:
There was a pretty major memory leak in jfs in the 2.6.8 kernel. This one-line fix is in the 2.6.9 kernel. I'm guessing that this would explain the problem you are seeing. http://www.kernel.org/git/gitweb.cgi?p=linux/kernel/git/tglx/history.git;a=commitdiff;h=fcc1fcc376bb1fe8ed7609b07931fc5bd774943a
