Exception while selecting a document frequently (every 1 minute)

While selecting same document from couchbase multiple time every 10 seconds gives following exception. It is just a simple select query using use keys, we get the same error even if we execute ‘Select 1’. Note: it comes one time out of 5 or so. can you please what we can do to resolve this issue.

“Message”:“An error occurred while sending the request.”,“Data”:{},“InnerException”:{“ClassName”:**“System.IO.IOException**”,“Message”:"The response ended prematurely.

Detailed Error:

Hello @kjindal2003 can you please provide a little more details like SDK version used , Server version, development environment etc.

@kjindal2003 -

The error indicates that the connection is likely be closed for some reason while the query is being executed. It could be any number of reasons; I would ensure that the app itself is not doing this by call Dispose on the ICluster or its not going out of scope.

@kjindal2003 Is your problem resolved? What was solution.
I too face this issue while querying from couchbase with same documentId. It suceeds 4 out of 5 times but fails once with above error you mentioned.

What SDK version are you using? If your on an a version earlier than 3.2.5, then try upgrading to that version or the latest.
