emacs is now using 98.1% of a P4 3GHz while apparently doing
nothing. It is continuously using more than 50%.
Here's the output of top:
26022 rmel 39 19 104m 37m 10m R 98.1 1.9 51:01.88 emacs
One of my co-workers is logged into my machine running emacs and
it is his session that is hogging the CPU. I just went and talked to him
and he wasn't doing anything in that session. He had left the emacs
code browser open, so I asked him to deactivate it to see if that would
make the problem go away. It did not. Is there a way to get emacs to
profile itself while this problem is happening so I can provide some
more useful debugging info?
Thanks,
David

Is your co-worker using an old version of semantic?

semantic-version is a variable defined in `semantic.el'.
Its value is "2.0pre3"
It looks like there was a pre4 that came out a few days
after emacs 22.1. I'll try having him upgrade to that.
Thanks,
David

Although I don't have enough statistics to say for sure,
changing from cedet 1.0pre3 to pre4 seems to have
fixed the emacs CPU hogging problem. Thanks for
the feedback. If I see the problem again, I'll follow
up again after running gdb on emacs as RMS
suggested.
Thanks,
David
