I'm not sure if it's related, but I did enable the "Keep only unread messages"
option in the "Ofline & Disk Space" section of the prefs before seeing this
problem.   Disabling the option does not fix the problem, though.

I am seeing this currently with alt.music.mp3 on Linux, trunk CVS.
NNTP log and profile forthcoming

Attachment: profile during attempt to open alt.music.mp3

using news.freeserve.co.uk, profile of Mozilla whilst it is
looping at 100% CPU. I didn't get any output in my nntp log
for some reason.

when I remove the .msf file I don't have the problem. I suspect the file
got corrupt after I ran out of disk space during a previous session ?

.msf file : http://movementarian.org/alt.music.mp3.msf.gz

bug 134866 is possibly a dupe of this.

I experienced the same problem when subscribing to a large newsgroup (13000
messages). While Mozilla was downloading headers, it was using 100% CPU and the
UI was completely unresponsive (no redraw). Given that I have a 512 kbit DSL
connection, this operation really should not be CPU-bound !

W2KSP3, Mozilla 13b 20030210
( Maybe this is no longer "NEW" :-)
I'm having the same problem, only up to 99% CPU (as low as 87% when other
taskbar resident process is running.)

This is a new setup, with freshly re-installed OS and clean first install of
Mozilla 1.3b. There is only one irregularity in the setup of Mozilla, which may
give a programmer a clue about where the bug comes in.

Yesterday, while reinstalling all my applications, before I had figured out
(again) how to set up Mozilla to use my mail profile and data saved on disk, I
was checking the Web for updates to WordPerfect. At that time I got onto the NG
fine in the temporary default profile Mozilla had set up for me, and posted a
question. Then, after I got my old Mozilla profile set up (and deleted the
default profile), I cannot get any messages from the NG; trying to see any
messages hangs Mozilla (but not necessarily other programs already running).

I set up a W2K user account for myself, invoked Mozilla Profile Manager, deleted
the default profile and associated files, and directed PM to the old profile.
Other NGs work OK, and I can subscribe to new NGs, as I just subscribed again to
netscape.mozilla.public.general. There is a problem at the Corel NG. I can
subscribe to the Quattro NG, but it does not list any messages. (I don't think
I've used the context menu for "Get Messages for Account" on that NG, and I'm
afraid that maybe it will hang now if I try that. When unsubscribed from and
resubscribed to the WordPerfect NG, I got the same hangup.

I deleted the Corel account and re-subscribed, and now it is working.

No response, and I can't reproduce this with build 2004-05-12-08 on Windows XP
