Story Points:

Description

Most services on CNs run in JVM instances, each with separate restrictions on memory use.

Current configurations were mostly based on defaults and have not changed much despite significantly higher memory use for systems such as Solr and Hazelcast.

The goal of this story is to evaluate the memory configuration of each JVM instance on the CNs and tune as necessary with the primary goal of avoiding out of memory errors, secondary goal is improving performance.

Note that with increased heap allocation, garbage collection may become a significant bottleneck, with application freeze in the order of several minutes possible or likely with higher heap allocations (e.g. 16GB)
