I see warning messages in the log from a logger named DatasourceImpl.java:300 I’ve seen that same logging in other threads but have yet to see anything about what is generating them. The latest message I have seen is as follows: java.sql.SQLException: Cannot get a connection, pool error Timeout waiting for idle object at org.apache.commons.dbcp2.PoolingDataSource.getConnection(PoolingDataSource.java:142) at org.apache.commons.dbcp2.BasicDataSource.getConnection(BasicDataSource.java:734) at com.inductiveautomation.ignition.gateway.datasource.DatasourceImpl.getConnectionInternal(DatasourceImpl.java:300) at com.inductiveautomation.ignition.gateway.datasource.DatasourceImpl.runTest(DatasourceImpl.java:253) at com.inductiveautomation.ignition.gateway.datasource.DatasourceManagerImpl$FaultedDatasourceRetryer.lambda$newRetryRunnable$0(DatasourceManagerImpl.java:1096) at com.inductiveautomation.ignition.common.execution.impl.BasicExecutionEngine$TrackedTask.run(BasicExecutionEngine.java:582) at java.base/java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source) at java.base/java.util.concurrent.FutureTask.runAndReset(Unknown Source) at java.base/java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(Unknown Source) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.base/java.lang.Thread.run(Unknown Source) Caused by: java.util.NoSuchElementException: Timeout waiting for idle object at org.apache.commons.pool2.impl.GenericObjectPool.borrowObject(GenericObjectPool.java:321) at org.apache.commons.pool2.impl.GenericObjectPool.borrowObject(GenericObjectPool.java:428) at org.apache.commons.pool2.impl.GenericObjectPool.borrowObject(GenericObjectPool.java:232) at org.apache.commons.dbcp2.PoolingDataSource.getConnection(PoolingDataSource.java:134) ... 11 more 8.1.17 (b2022051210) Azul Systems, Inc. 11.0.15 ![20230726error](https://us1.discourse-cdn.com/inductiveautomation/original/3X/0/a/0a4e37dad34370513a2fe64c105315c26162621e.jpeg) ![20230726error2](https://us1.discourse-cdn.com/inductiveautomation/original/3X/6/a/6a76da3cfd8ae8f39a906ff656f5f1647f5bb84f.jpeg) ![20230726error3](https://us1.discourse-cdn.com/inductiveautomation/original/3X/5/6/560b3bbcfb67b83a171cee5638ec535765938712.jpeg) Can anyone give me some insight into this logger? ---

That log message you posted refers to your faulted MSSQL database connection. I believe either the DB is down/unreachable, or you may have maxed out your connection pool(default is 8 max). Maxing out your connection pool can lead to your database connection faulting. > [@DONGHO\_HEO](#): > > “Delegate is not set…” Where did you see this? ---

What are the contents of the `$IGNITION_INSTALL_DIR/user-lib/jdbc` folder? ---
