Typically this isn't reproducible. I rebooted into the latest F20 kernel 3.16.3-200.fc20.x86_64 and hit that URL in Firefox, then only I noticed was the first time I loaded the URL was that the mem field of the TCP line in /proc/net/sockstat spiked up to a little over 5000 before coming back down. But no noticeable ill effects. I rebooted back into 3.17.0-rc6-00180-g452b6361c4d9, but this time Firefox loaded the URL without issue. Rebooted back and forth a couple of time but couldn't hit the problem, maybe there's some other factor involved. I've too the opportunity to build the latest kernel 3.17.0-rc6-00247-g005f800508eb. I'll see if I can hit the problem again after the machine has been up a while. Cheers, Andrew
