Known Affected Versions:
11.6.0, 11.6.0 HF1, 11.6.0 HF2, 11.6.0 HF3, 11.6.0 HF4, 11.6.0 HF5

Opened: Jul 14, 2015

Severity: 3-Major


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.
