What to do when Photon locks up?

[6.21 PE]
I occasionally get Photon lockups, usually when Mozilla is
running. Most recently, when this happened, I saw the
following situation:

  • The machine involved would not respond to mouse movement
    or keyboard input.
  • The machine was still up on the net, and I could execute
    remote commands on it with “on”, such as “on -f node ps”
  • No process was using any significant CPU time.
  • Killing Mozilla’s process did not clear the problem.
  • “on -f node shutdown” caused a clean shutdown and reboot
    of the system.

What’s proper procedure in this situation? Is this a known
problem? Is there anything I should send in with a bug report?

Take a look in /var/dumps. Do you have an io-graphics.core?
If you can telnet in you should be able to restart io-graphics
without any issue. I belive that PatchB fixed this font issue that
mozilla tickled.

Yes, there it is:

May 28 18:11 io-graphics.core

We’re still running the original 6.21. so that’s probably it.
Looking forward to 6.3.
