This might be related to a problem we've fixed about a month ago in the 
upstream kernel:

https://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=58af19e387d8821927e49be3f467da5e6a0aa8fd

The fix made it into Linux 3.1. Can you somehow give it a try? 
(Backporting to your F14 kernel should be fairly trivial, since it's a 
one-line change in tcp_minisocks.c.)
