RHEL6: Different NIC cards encounter TX and RX hangs
Issue
We have have 3 RHEL servers : 2 x RHEL 6.5 / 1 x RHEL 6.6 server which resets the NIC adapter. This leaves the servers useless. They are HP G8 servers with Intel 10Gbe (ixgbe) NIC's. They act as IBM Tivoli Storage Manager (TSM) backup servers. Huge amount of data is received/sent over the NIC.
The one server was initially delivered with an Emulex NIC but this failed with the same error, under less network load. An Intel NIC was installed to replace the Emulex NIC .
This is NOT a hardware problem. It's unlikely so many NIC's/cables/SFP's should be broken.
Environment
- Red Hat Enterprise Linux
- RHEL6.5 and RHEL6.6 kernels
