Symptoms

The BIG-IQ REST framework JVM process (restjavad) fails intermittently when RAM memory is low or during highly intensive memory operations.

Impact

BIG-IQ management interface and device management workflows are temporarily unavailable while restjavad restarts.

Conditions

This happens when there is not enough RAM available for the normal operation of the BIG-IQ REST framework, especially in environments with a relatively large number of managed BIG-IP devices and related configuration objects, and a high volume of collected statistical data.

Workaround

Increase the physical memory (RAM) that is available for BIG-IQ (hardware or virtual).

Fix Information

This issue is fixed and restjavad no longer fails under these conditions.
