Opened: Mar 01, 2019
Severity: 2-Critical

Symptoms

When TMM detects a compression offload device hang it does not invoke the configured high availability (HA) action.

Impact

The configured HA action does not occur when a compression offload device hangs. Clients compression requests eventually time out.

Conditions

This occurs when the following conditions exist: -- BIG-IP Virtual Edition (VE) Cryptographic Offload is licensed. -- BIG-IP VE VM has been assigned QuickAssist Virtual Functions (VFs). -- A QuickAssist endpoint associated with one of the VFs hangs. -- BIG-IP VE executes compression operations.

Workaround

Disable the pfmand by running the following commands: tmsh modify sys db pfmand.healthstatus value disable tmsh save sys config The configured HA action will now occur when a compression offload device hangs. Note: The pfmand daemon is not needed for BIG-IP VE, so disabling the db variable has no impact for BIG-IP VE configurations.

Fix Information

None
