IssueThe concentrator service is unresponsive in Security Analytics 10.3.4, and the following blank error box pops up in Investigation: 
Investigation error
CauseThe session.cache.read.chunk may cause a bottleneck on the concentrator.  If it is incorrectly set, it can cause excessive memory usage for the concentrator service.
Resolution1) Open the Concentrator service Explore view.
2) Navigate to database->config
3) Locate two nodes named "meta.cache.read.chunk" and "session.cache.read.chunk" and change their value to 0.  This will reduce the amount of memory that the concentrator service is allowed to consume.
NOTE: This change takes immediately without restarting services or rebooting.
