i think this is an artifact of setting up heavily-used systems
combining venti, fossil, auth and cpu server.

sure crashing is antisocial. the alternative is to add very
large amounts of code to the kernel.
Swap doesnt work reliable here. :-(
I have disabled swaping and let the kernel kill the biggest process
skipping any critical server processes and it works well.
got ~100 days uptime and i use this machine for linuxemu
development/testing.
no adding very large amounts of code... maybe fix the swap... or even
remove it alltogether.
Back when this was first posted I wanted to protest the point that a
large kernel modification is necessary, since I figured you can do a
"good enough" job with just an interface to tell the kernel not to
kill the important server processes.
Obviously I decided to let it lie, but I just discovered this can be
done without modifying the kernel at all when I happened across an
interesting line in termrc:
/rc/bin/termrc:dontkill
'^(ipconfig|factotum|mntgen|fossil|cs|dns|listen|reboot)$'
The default cpurc doesn't use dontkill, but I suspect it could be a
big help for all-in-one servers. Figured I'd point it out as it seems
easy to miss.
... plus everyone can use a good scare every now and then, and what
better way than to resurrect sad commentry?
-sqweek :D
good to know :-)
