SAS Viya CAS Reporting Server Failure

[cmitch34]

We are experiencing numerous reporting server failures of 6-8 times a day requiring us to restart the reporting server. We are having a hard time determining what is causing this failure is. When looking through the logs, I did see this message though: 

Error gathering metadata information for custom - Table Metadata may be incomplete - DataQueryException: Unable to access

We are new with SAS and i am not entirely sure what this error is in reference to. This is causing cascading failures and other errors:

Can anyone please help????

I was able to determine what was causing this cascading failures,. its a java out of memory error. We dont even have that much data in SAS, does anyone know how to resolve or come across something like this:
