In some cases, a stuck crypto queue can be erroneously detected on Cavium Nitrox-based (Nitrox PX and Nitrox 3). When the tmm/crypto stats are examined, they show no queued requests. The following message appears in the ltm log: Device error: crypto codec cn-crypto-0 queue is stuck. tmm crash
The system reports device errors in logs, and takes crypto high availability (HA) action, possibly resulting in failover. Traffic disrupted while tmm restarts.
-- Running on one of the following platforms: + BIG-IP 800, 1600, 3600, 3900, 6900, 89xx, 2xxx, 4xxx, 5xxx, 7xxx, 10xxx, 11xxx, 12xxx, i2xxx, and i4xxx + VIPRION B41xx-B43xx, B21xx, and B22xx blades. -- Performing SSL. -- Under heavy load.
Modify the crypto queue timeout value to 0 to prevent timeouts using the following command: tmsh modify sys db crypto.queue.timeout value 0 To clear erroneously stuck queues, you must restart tmm or reboot the BIG-IP system. Note: Traffic is disrupted while during restarts.
The crypto driver now only examines requests in the hardware DMA ring to detect a stuck queue on Nitrox devices.
