IdB 4.1.3 SQL Agent:  The timeout period elapsed prior to obtaining a connection from the pool.

We use the SQL agent in IdB to read and write from a simulated SAP data source for testing. When exporting changes to the database via IdB, after approximately 100 exports, IdB starts reporting the following exception. When the IdB is stopped and restarted, a further 100 can be exported before the error reappears.

System.InvalidOperationException: Timeout expired.  The timeout period elapsed prior to obtaining a connection from the pool.  This may have occurred because all pooled connections were in use and max pool size was reached.   at System.Data.ProviderBase.DbConnectionFactory.TryGetConnection(DbConnection owningConnection, TaskCompletionSource`1 retry, DbConnectionOptions userOptions, DbConnectionInternal oldConnection, DbConnectionInternal& connection)   at System.Data.ProviderBase.DbConnectionInternal.TryOpenConnectionInternal(DbConnection outerConnection, DbConnectionFactory connectionFactory, TaskCompletionSource`1 retry, DbConnectionOptions userOptions)   at System.Data.ProviderBase.DbConnectionClosed.TryOpenConnection(DbConnection outerConnection, DbConnectionFactory connectionFactory, TaskCompletionSource`1 retry, DbConnectionOptions userOptions)   at System.Data.SqlClient.SqlConnection.TryOpenInner(TaskCompletionSource`1 retry)   at System.Data.SqlClient.SqlConnection.TryOpen(TaskCompletionSource`1 retry)   at System.Data.SqlClient.SqlConnection.Open()   at Unify.Framework.Data.DbConnectionExtensions.OpenIfClosed(IDbConnection connection)   at Unify.Framework.Data.SqlServerDataControl.CreateComponent(Boolean factoryInformation)   at Unify.Framework.Data.AdoNetDataControl.ExecuteDataSetQuery(DataSet resultSet, String commandText, IEnumerable`1 parameters, String[] tableNames, CommandType commandType)   at Unify.Framework.Data.AdoNetDataControl.ReturnDataSetQueryT(String commandText, IEnumerable`1 parameters, String[] tableNames, CommandType commandType)   at Unify.Product.IdentityBroker.DirectCommunicatorBase`1.GetEntitiesDataTable(ICollection`1 keyList)   at Unify.Product.IdentityBroker.DirectCommunicatorBase`1.UpdateEntities(IEnumerable`1 entities)   at Unify.Product.IdentityBroker.DirectReadWriteConnectorBase`1.UpdateEntities(IEnumerable`1 entities)   at Unify.Product.IdentityBroker.ConnectorToUpdatingConnectorBridge.UpdateEntities(IEnumerable`1 entities)   at Unify.Product.IdentityBroker.EventNotifierUpdatingConnectorDecorator.UpdateEntities(IEnumerable`1 entities)   at Unify.Product.IdentityBroker.Adapter.UpdateEntities(IEnumerable`1 entities, EntityToConnectorEntityBridge[]& connectorEntities)   at Unify.Product.IdentityBroker.Adapter.UpdateEntities(IEnumerable`1 entities)   at Unify.Product.IdentityBroker.Adapter.UpdateEntity(IAdapterEntity entity)   at Unify.Product.IdentityBroker.AdapterNotifierDecoratorBase`1.UpdateEntity(IAdapterEntity entityToSave)   at Unify.Product.IdentityBroker.CompositeAdapter.UpdateEntity(IAdapterEntity entity)   at Unify.Product.IdentityBroker.AdapterNotifierDecoratorBase`1.UpdateEntity(IAdapterEntity entityToSave)   at Unify.Product.IdentityBroker.LDIFAdapterBase.HandleExportUpdate(IAdapter adapter, IAdapterEntitySaveChange pendingUpdate)   at Unify.Product.IdentityBroker.LDIFAdapterBase.ExportChanges(ExportedLDIFForAdapter exportedLdifForAdapter)   at Unify.Product.IdentityBroker.LDIFAdapterServiceHostDecoratorBase.ExportChanges(ExportedLDIFForAdapter exportedLdifForAdapter)   at SyncInvokeExportChanges(Object , Object[] , Object[] )   at System.ServiceModel.Dispatcher.SyncMethodInvoker.Invoke(Object instance, Object[] inputs, Object[]& outputs)   at System.ServiceModel.Dispatcher.DispatchOperationRuntime.InvokeBegin(MessageRpc& rpc)   at System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage5(MessageRpc& rpc)   at System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage41(MessageRpc& rpc)   at System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage4(MessageRpc& rpc)   at System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage31(MessageRpc& rpc)   at System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage3(MessageRpc& rpc)   at System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage2(MessageRpc& rpc)   at System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage11(MessageRpc& rpc)   at System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage1(MessageRpc& rpc)
