Application is unable to use the UCP threadpool after a recent upgrade to JDBC 184.108.40.206 and UCP 220.127.116.11. Database version is 18.104.22.168.
Thread pool is at maximum capacity (24 in this case) due to waiting tasks, and UCP results in not allowing any further connections.
The issue occurs when Fast Connection Failover (FCF) is enabled.
