We have a server connected to a 4900M at 10gig and it's generating the following alerts:
Feb 21 10:19:31.992: %C4K_HWPORTMAN-4-BLOCKEDTXQUEUE: Blocked transmit queue HwTxQId7 on Switch Phyport Te1/1, count=102512 I found https://supportforums.cisco.com/docs/DOC-4766 after some searching: ---- Resolution Perform these procedures as a workaround for this issue: 1. Issue the shut /no shut commands to recover the port and configure both ends to operate at the same speed and duplex, as per Cisco bug ID CSCsb62330. 2. If the problem persists, move the connected device to another port and see if the problem also happens there. 3. Issue the hw-module reset command to reboot the switch or reset the line card, as a final attempt to unblock the Transmit (Tx) queue. Alternatively, upgrade the the Cisco IOS(r) version to the 12.2(25)EWA2 and 12.2(25)SG releases, which have the fix for this problem, as per Cisco bug ID CSCsb01311. ---- I'm running 12.2(44r)SG5 and do not have any qos features in the config, so I'm running whatever is default. The server is a centos 5 system running an off the shelf Intel X520-SR1 nic. It's gone unreachable so I need to go to the data center to see what's on the server's screen but figured I'd see if I need to make some changes to it before heading over.
