Resolution

The value of parallelDbConnections determines the maximum amount (= largest possible size of the connection pool available to a JCP) of parallel database sessions opened by a single JCP to the database.

This value is per-process. 

If all connections are busy a jetty thread has to wait until a connection is added back to the pool.
