I can replicate. In TB 6.0.2 I show over 248K in unread messages.
Normally when I have that many in a newsgroup that I frequent often, I
'mark as read by date'. I just did this to mark all as read since the
17th. As soon as it started I got the javascript error:
A script on this page may be busy, or it may have stopped responding.
You can stop the script now, or you can continue to see if the script
will complete.

Script: chrome://messenger/content/markByDate.js:137

At that point I can either elect to stop the script or continue. I
select 'Continue' TB greys out for a second (expected), and I get the
message again (not expected). This time I tick the 'Don't ask me again'
box and again click 'Continue'. TB greys out (expected as it is sucking
CPU & it takes a very long time to go through 248K+ headers), but no
more script error, and finally my unread count is 15. So give that a try
Jim & see if it finally completes for you.

I've not tried the workarounds suggested here:
