ubuntu server 9.04 rsync/ext4 bug

I've noticed an occasional problem running rsync. When running rsync,
sometimes the system becomes unresponsive. Running top, I notice the
system load continually increasing and I cannot kill rsync (even with
sudo kill -9 <rsync_process_id>). I have to reboot or shutdown the
system to recover. Rsync is basically syncing from another host (rsync
-Pav some_host::dir2sync/ /local/dir/) or from a locally mounted cifs
share (rsync -Pav /mnt/win_share/ /another/local/dir/). My local
filesystems are ext4. This seems to happen when running 2 or more rsync
processes at the same time. I didn't have this problem with rhel5.
Any suggestions to help debug this problem. I have never run a system
trace or similar debug tool. If that would be useful, let me know.
