any other half-dead servers lately?

I have a machine running OS X Server v. 10.4.7. On Tuesday,
Wednesday, Thursday, and again today -- but not even close to the
same time -- the machine crashed.

Except, not really. I could ping it. Ok... but I could also telnet
to a service port (25, 80...) and instantly get a socket
connection... but the service would not "talk" to me after initial
connections. (I could even walk up to the machine and move the mouse
and finder&app windows around, but trying to *do* anything in any app
would cause the app to freeze w/ the spinning colorful ball.)

Meanwhile, I found that a colleague across campus (actually, at the
Richmond Field Station) saw THE SAME THING happen to a somewhat older
Dell RedHat machine on Wednesday and Thursday. He could telnet to a
socket and get an instant, successful connection, but no responses
after initial connections.

We're each going through the usual drill to diagnose, but I thought
I'd send a quick post out across campus on the odd chance that this
same thing is happening to other machines.

(We each have other machines configured similarly, but they have NOT
gone into the semi-frozen condition like these two.)

So, if you have any servers that have gone in to a similar semi-
frozen state in the last couple of days, please drop me a line.

Thanks,
-Greg
