Howdy.

My wife was sending a particularly large email last night (160 lines)
and decided to spell check it.

It checked 4 or 5 spellings, then hung and never returned to
the browser.

I checked the server, and sure enough the process was eating
CPU by the truckload.

I did this three times last night to reproduce the hang. All three
times I was sucessful. All three times used a different process
(because I killed the previous CPU hogs).

Now, from work, I can't reproduce the hang at all. Perhaps it has
something to do with the browser I use at home? I'll try again
from home later today.

Just thought you folks might like to know.

Is there a way to debug things like this and figure out what is
causing the hang? Can I run something like ktrace on an already
running process? Can I somehow compile sqwebmail with
debugging code so that I can trace the sqwebmail process when
a CPU hog appears?

I get sqwebmail CPU hogs every few days on my server, so I'd really
like to figure out what the problem is. My box is a FreeBSD 4.8-
RELEASE box. And I've been experiencing these sqwebmail hangs
for months now. And I'm not even running FastCGI. :)
