Com.f5.rest.workers.storage.ThreadPoolStorageRequestProcessorjava.lang.OutOfMemoryError: Java heap space


REST Framework not being available, causing the "Device Management >> View" screen to show failure.


Under HA pair setup, over the period of 6 months or more, the device-discovery-tasks accumulate, causing restjavad to fail repeatedly, once every 20 seconds, logging the message: "com.f5.rest.workers.storage.ThreadPoolStorageRequestProcessorjava.lang.OutOfMemoryError: Java heap space".


Run clear-rest-storage once a week and try increasing the restjavad.extramb BIGdb variable from 192 to 768.
