[Forums] Timer resulted in The underlying connection was closed: An unexpected error occurred

Hi Guys,

I having a timer error when the timer is running :

[1] The underlying connection was closed: An unexpected error occurred on a receive.
   at System.Web.Services.Protocols.WebClientProtocol.GetWebResponse(WebRequest request)
   at System.Web.Services.Protocols.HttpWebClientProtocol.GetWebResponse(WebRequest request)
   at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters)
   at OutSystems.Scheduler.Core.TimerHandler.ExecuteTimer(String ssKey, Int32 timeout, Int32 tenantId)
   at OutSystems.Scheduler.Core.TimerJob.Execute()
   at OutSystems.Scheduler.Core.SchedulerProducerConsumer`1.Execute(Job job)

[2] Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.
   at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size)
   at System.Net.PooledStream.Read(Byte[] buffer, Int32 offset, Int32 size)
   at System.Net.Connection.SyncRead(HttpWebRequest request, Boolean userRetrievedStream, Boolean probeRead)

[3] An existing connection was forcibly closed by the remote host
   at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size)

This timer should run once every month, but it'll call extensive insert data to entity (+/- 1.000.000 record).

Does this happen because the database connection timeout ? or other things ?

If this because of database connection, any suggestion on fixing this on cloud environment ?

Thanks Guys
