Default value of device-request timeout factor might cause false alert: Hardware Error ni3-crypto request queue stuck.
The /var/log/ltm log contains the following message: Hardware Error(Co-Processor): n3-crypto1 request queue stuck. tmm will be in failure state.
In case of heavy SSL traffic, Cavium Nitrox SSL hardware accelerator card might need more time than the default interval to complete the encryption or decryption.
Use tmsh to increase the device.request.timeoutfactor db variable to allow more time for encryption or decryption to complete. For example, to increase device.request.timeoutfactor to 200, run the following command: tmsh modify sys db device.request.timeoutfactor value 200. To clear erroneously stuck queues, you must restart tmm or reboot the BIG-IP system. Note: Traffic is disrupted while during restarts.
The default value of device.request.timeoutfactor is now sufficient to allow the Cavium Nitrox SSL hardware accelerator card to complete the encryption or decryption as expected.
