This set of log messages has been logged every 10 minutes since then. Any ideas?

This is redhat enterprise 3.6, kernel 2.4.21-37.ELsmp, GFS 6.0.2.27-0. GFS was built from the source. There are 2 partitions in the admin pool, the second was added a week or so ago. I tried to unmount it, but the umount failed because of the processes that are stuck in device waits.
