This should be fixed in 2.6.25-release
Are you using the default congestion control (cubic) or did you change to reno?
I haven't made any changes... this was a fresh rawhide install as of 4/7/2008. I'm running 2.6.25-0.218.fc8.git7.fc9.i686 right now. Is that new enough to have the fix? I haven't seen the issue at all in this version which has been running for almost 2 days.
This should be fixed in 2.6.25-final. Reopen this bug if it happens again.
