[rabbitmq-discuss] RabbitMQ Flex Client - TCP CHECKSUM INCORRECT

Mon Sep 1 05:06:28 BST 2008

IIRC, the Wireshark/Ethereal help says this occurs when the checksum
calculation is offloaded to the Ethernet hardware and doesn't mean much in
this case... but if I were you I would check the help just to make sure.
It's been a while since I looked at it and I could be wrong.
