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.
