Because the home server didn't respond to *another* request.
Each request has a timer. If the home server doesn't respond within that time, then it is marked "zombie".
Hmm. Given that the servers are lightly loaded, I guess we are looking at packet loss over the network? I have no idea if our networking people can 'detect' something like that, but I guess monitoring traffic coming out of the proxy and going to the home server should show if a packet is lost somewhere. Many thanks for all the replies. We always have at least one home server 'alive' according to FR so this has not been a problem for our users. It just seemed a bit odd behaviour when we looked into the log messages more closely. Thanks, John. -- John Horne, University of Plymouth, UK Tel: +44 (0)1752 587287 Fax: +44 (0)1752 587001
