From what I can tell, this was due to a VM exhaustion problem, and I don't see an actual patch that went in to fix this for 2.1 (looks like it was closed as NOTABUG, though there is an errata attached). My suggestion is to update to a newer kernel altogether and try tuning the VM such that pagecache is flushed out more aggressively. Opening a case with RH support with some specifics about your situation would probably be the best thing if you're not certain on how to proceed. In any case, RHEL3 is closed for anything but catastrophic bugs. Closing this as NOTABUG unless you have some information to the contrary.
