Jacob,
It looks like you're using a NIC with the e800013fd firmware from last summer, and from a separate message that you saw these issues with both the 1.2.2-k and the 1.2.37 version drivers. I suggest the next step would be to update the NIC firmware as there are some performance and stability updates available that deal with similar issues. Please see the Intel Networking support webpage at
https://downloadcenter.intel.com/download/24769 and look for the NVMUpdatePackage.zip. This should take care of several of the things Stefan might describe as "sketchy" :-).
