Description

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:

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();

and then performing this code three times:

IObjectId id = session.CreateObjectId("0923dba58001468a");
ob = session.GetObject(id) as IDocument;
str = ob.GetContentStream();

The first two calls complete quickly. The third call raises an exception after thirty seconds:

DotCMIS.Exceptions.CmisRuntimeException {"Timeout"}
