RTP panics when telnet sessions quit?

I’m seeing something relatively repeatable and very strange on one of my
RTP boxes. I normally work on the RTP box by opening a telnet connection
from elsewhere. This works just fine until I disconnect the telnet
sessions. After I disconnect, I find that no further telnet sessions can
be initiated (by myself or by anyone).

If I go to the console, I find that photon seems to have died and RTP
has gone back into text graphics mode. The latest messages on the text
display are always the same:

io-graphics received signal 11
IP: 0 ref: 0

Has anyone else seen this? The behavior is dreadfully repeatable on this
box and it’s interfering with my ability to work at all hours of the
night (heh). Any suggestions for tracking down the cause or fixing it?

When working on graphics drivers, I telnet to the test machine all
the time…

Did you initiate the Photon session from the telnet session?

Can you post the output of the ‘pci’ command?

No. Photon started as part of the boot process for the machine.

has gone back into text graphics mode. The latest messages on the text

I regret that I cannot. It turns out that the PC in question has other
problems (apparently, the designers didn’t see fit to connect 3.3V to
the PCI bus!). So, we’ve abandoned that machine. Sorry.

However, I am seeing another piece of annoying behavior on the machine
to which we’ve moved the RTP installation. Every night at about
22:15(PT), RTP seems to shut down to any net sessions. It refuses new
telnet connections, existing telnet sessions are indefinitely suspended,
the box itself will not ping anyone else, and web connections don’t go
through.

We’ve not been able to find any activity that comes up on or about 22:15
(our first thought). So, I’m left with trying to figure out if RTP is
going down for some reason. Any hints where to look?
