Hello!

 

We're running into an issue on one of our cDOT Cluster (8.2.3P2) with sporadic closed connections as indicated by the error below:

 

24    6:54:49 PM    Console    Failure        An unhandled exception occurred: Exception: Error number: 0
25    6:54:49 PM    Console    Failure        [Filer = 10.188.120.220] <sis-status><path>vol_name</path><verbose>True</verbose></sis-status> ---> NetApp.Manage.NaException: Failed invoking API ---> System.Net.WebException: The underlying connection was closed: The connection was closed unexpectedly.
26    6:54:49 PM    Console    Failure           at System.Net.HttpWebRequest.GetResponse()
27    6:54:49 PM    Console    Failure           at NetApp.Manage.HTTPClient.DoRequest()

 

The workflow is a C# based program that uses our SDK and API calls on a W2K R2 based host.

 

While dedupe is running on a given Volume we check every ten seconds if dedupe is completed. The command succeeds most of the time but not always. After the error above we then get error below:

 

Command was invoked on filer: 10.188.120.220
not authorized for that command ---> NetApp.Manage.NaApiFailedException: not authorized for that command   at NetApp.Manage.NaServer.InvokeElem(NaElement element)

 

Any idea what would cause the connection to be closed?

 

I cannot find any errors about both the closed connections nor what looks like an RBAC issue on the Cluster itself (mgwd, debug, messages). I do see the incoming requests in the apache log.

 

Any help is appreciated!

 

Thanks,

 

//Mike
