I seem to get this error when deployed code to our linux environment, not sure what does this mean
Please can someone help me to explain and possible fix?

Check your maximum transaction count. It seems your setup has only one connection for your datasource and 0 is available. This means you have no idle connections.

myDataSource.setMinPoolSize(0);
myDataSource.setMaxPoolSize(5);
