Thanks for the reply. Forgot to mention, our machines are all i386 with the problem -- so are the ones without the problem. Yes, I found that patch too and tried it on one of the servers -- no joy. Guess we'll continue to wait also for now. Maybe 7.2/i386....or, until someone finds the solution since we're out of ideas and stuck with 6.3 in order to use dump that we have trusted.
