hmm, could you try to reproduce this without eclipse/jvm?
(some small C programm or perl script will do)

maybe the patch isn't the only variable in this game,
maybe you patched another (newer?) kernel with v1.00?
It is possible that v1.00 is the reason, but it is
unlikely, as the network code should be the same,
nevertheless I would appreciate further testing ...
so could you either provide kernel versions or do
some testing on your own, to narrow down this issue?
TIA,
