Wild guess: Is it possible that your Linux guest is on the eligible list when it appears to be frozen? Issuing CP IND Q from a priveliged user when this happens will show this.

I've done this before by accident and caused no end of confusion until I tracked it down. You'll see intermittent behavior like that due to ARP wars where each system tries to own the IP, and it depends on the local ARP cache of the system you're connecting -from- which one gets picked. This is also relevant for gateways - if you bring up two gateways with the same IP, everything on the network that routes through that GW is going to have the same intermittent issue (but not, of course, the same systems at the same time. That would be too easy to track down.) Might be a wild goose chase but it's pretty easy to check, so it's a good starting point. -m On Tue, Nov 02, 2004 at 01:55:52PM -0700, Seader, Cameron wrote: > Greetings, > I am having a strange issue with my linux guests.
