We have not tried the 0.8 kernel extensively, but there is nothing in the release notes that seems related. Our next trial will be with FC6. Unfortunately it can take days for this problem to show up.

A previous responder suggested swapping CPU's or RAM around. The RAM has been shuffled and in some cases replaced (the vendor replaced all the 1GB DIMM's with 2GB). These problems are occurring across 25 machines, so it does not seem to be isolated bad components.
