Opened: Jun 23, 2016

Severity: 3-Major


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


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


Very rapid queuing of concurrent accelerated compression requests.


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