Sounds like hardware checksum failed for tcp v4. The NIC (network interface card) may perform checksums on incoming and / or outgoing network traffic.
Network problem? Cabling? NIC defective?

Hello,

I agreed with JP, and you might be able to fix your problem by

1. upgrade your NIC divers

Or

2. Upgrade your kernel to newer version.

you can also check your current network status about checksum errors with following command.

#netstat -s|grep -F -e 'bad segments'

I hope this helps,

Sung
