Ok... there's nothing in here on what happened to cause it, nor if it's reproducable. Would that information be available?
You know as much as we do; this occured during normal machine operations, no obvious trigger. The server was obviously running an oracle database, but beyond that, this "just happened".

The correlations between the 2 tickets are that both machines is running Oracle and using e1000 cards.
We could never reproduce this problem in order to debug it. If this happens in RHEL3 please open up a separate bug. Larry Woodman
