Assertion Failure



I got this.. The system was usuable, but not very.  If I tried to access the
ext3 volume, it would hang.  Reboot hung too, complaining about too many
open files.  Any ideas?  I have no idea what triggered it; this is a big
file/web/mail server, with all of that on the ext3 volume.  And I've never
run ksymoops before, but I think I did it right.
