Symptoms

Accelerated compression requests that exceed 128 in-flight requests can cause a watchdog event.

Impact

TMM generates an HA failover driven by the accelerated compression watchdog timer.

Conditions

Very rapid queuing of concurrent accelerated compression requests.

Workaround

Disable accelerated compression by disabling hardware accelerated compression with: % tmsh modify sys db compression.strategy value softwareonly

Fix Information

Apply a constraint on accelerated compression request DMA ring so no more than 128 in-flight requests are queued at any one time.
