Hi @Andy_Wang,

What version of the .NET SDK are you using? In the latest release (2.7.11), this line would not work:

There is no overload of ClusterHelper.Initialize that accepts a string. This may not solve your problem, but you should probably upgrade to the latest .NET SDK.

thanks for your attention,my client version is 2.7.10, server is couchbase-server-enterprise_6.0.2-windows_amd64.msi].it works normally in Initialize and normally at the beginning of 6/7 minutes,after that when i use multi thread ,every thread has different cycle time, when the exeption happens some call getdocument is ok,others fall,but they all use same bucket stored in ClusterHelper，i really don’t know why.The exeption object“/7198b36e_0d7c_4671_8af4_08296fde986b/fmmiypfup+cdh8bmkbetleer_33.rem”(has disconneted or not in server) seems like that in server part some object has been disposed.

can you take a look whether my cofiguration is wrong,and which can affect server object lift time.
