Opened: Jul 14, 2015

Severity: 3-Major

Symptoms

The AuthTokenWorker creates new indexed state objects. Some are unable to be deleted because they are shared between instances. Generations of tokens build up, however the generational scavenger only runs when disk space is tight. Restjavad can run out of memory before the scavenger ever gets to run.

Impact

Generations of tokens build up

Conditions

Tokens shared between instances

Workaround

N/A

Fix Information

Add another trigger to the generational scavenger such that it also triggers when memory is tight as well as when disk space is tight.
