Resolve Spectrum OLockException: Not more resources available in pool

User is running a web service in which they are running into this error message: OLockException: No more resources available in pool

User edits \server\app\conf\ orientdb-server-config.xml file by editing the db.pool.max by increasing the value to 30 or 100. Increasing the db.pool.max value does not help and the OLockExceptions still occurs.

After some investigation, items are not being added to a cache that should be. Therefore, each request for information loads that information from the Orient database. Also, the user has a custom security role that has access to certain db resources and the ability to execute services.
