Thanks for getting back to me.
I've been running the system as a web server for 8 years round the clock
and this is the first and only time I had an unexplained kernel crash.
I sent the bug in because I was unable to interpret the dump and I was
actually worried someone had hacked my system causin
Public bug reported:
Have the logs around this. Failed while running unattended.
