Cause:
Potential incompatibility with older Virtual Machine NIC driver.
Resolution:
Looking at DCE log files on a VM install, you may see an error similar to the following: kernel:
e1000 0000:02:00.0: eth0: Detected Tx Unit Hang
This has been seen in VMware ESXi 5.0. It appears to be most prevalent when attempting a DCE backup. In cases where this issue does exist, an upgrade of the VM host to ESXi 5.5 has been seen to resolve this error.
