Florian Müller commented on CMIS-559:
-------------------------------------
When you get a content stream, you have to consume and close the stream.
Otherwise socket connections to the server remain open and .Net limits the
number of concurrent connections to a server to 2 connections.
You can also increase the limit by setting the
ServicePointManager.DefaultConnectionLimit property [1].

> Timeout when fetching documents
> -------------------------------
>
> Key: CMIS-559
> URL: https://issues.apache.org/jira/browse/CMIS-559
> Project: Chemistry
> Issue Type: Bug
> Components: dotcmis
> Affects Versions: DotCMIS 0.4
> Environment: Windows, Visual Studio 2010 C# client application
> Reporter: Katie
>
> DotCMIS.Exceptions.CmisRuntimeException with "Timeout" is raised when an
> attempt is made to fetch a third document within several minutes. All
> subsequent operations then also time out, until several minutes have passed.
> This can be easily reproduced by initialising a session:
> {noformat}
> private ISession session;
> private SessionFactory factory;
> private Dictionary<string, string> parameters = new Dictionary<string,
> string>();
> parameters[SessionParameter.BindingType] = BindingType.AtomPub;
> parameters[SessionParameter.AtomPubUrl] = dms_cmis_url;
> parameters[SessionParameter.User] = dms_cmis_user;
> parameters[SessionParameter.Password] = dms_cmis_password;
> factory = SessionFactory.NewInstance();
> session = factory.GetRepositories(parameters)[0].CreateSession();
> {noformat}
> and then performing this code three times:
> {noformat}
> IObjectId id = session.CreateObjectId("0923dba58001468a");
> ob = session.GetObject(id) as IDocument;
> str = ob.GetContentStream();
> {noformat}
> The first two calls complete quickly. The third call raises an exception
> after thirty seconds:
> {noformat}
