SqlTransaction problem after some time

Good morning, we are using SqlTableDependency into an always running Windows Service like a “notifications centralized service”; after about two days of always running we get a sql transaction exception, i logged also the SqlTableDependency status change:

[21:02:33] Status changed: STOPDUETOERROR [21:02:33] Error message: TableDependency stopped working exception: System.InvalidOperationException: This SqlTransaction has completed; it is no longer usable. at System.Data.SqlClient.SqlTransaction.ZombieCheck() at System.Data.SqlClient.SqlTransaction.Rollback() at TableDependency.SqlClient.SqlTableDependency`1.<WaitForNotifications>d__63.MoveNext()

Is maybe a sql transaction timeout problem or something like that in the sql server configuration?

Thanks very much in advance

Has anyone attempted to resolve this issue by having your application react to the SqlTableDependency OnError or OnStatusChanged events? I use a wrapper class over SqlTableDependency that has a Configure() method and a Start() method. Start() calls Configure(). The event handler for SqlTableDependency OnError events uses a Polly RetryPolicy to call the Start() method with exponential backoff until it returns without exceptions. I am accessing SQL Server instances over slow/intermittent/noisy links and this design works beautifully for us. The service is resilient without the need for external watch dog servicing.

@fluxium I am using an external service that reinitializes SqlTableDependency in a certain interval. This is very inefficient and we are having a lot of issues. Can you kindly share your solution?
