Symptoms

On a single node, Oracle Business Intelligence (OBI) 12c 12.2.1.2 and 12.2.1.3 queries that are cached intermittently fail with the following error



The reports are cached overnight by caching agents and may occasional receive the following full error across random periods.
The error will go away after recycle the services, which in turn deletes the existing cache and clears the memory. Upon re-running the same report that generated the error previously the report will now run.
The error does not always occur after the cache is generated in advance overnight by caching agents, this is a very random error that occurs.
The issue is only occurs when multiple unions are used in complex queries.
