Nieldy -
Here is some information for enabling logging: http://docs.couchbase.com/couchbase-sdk-net-1.3/#appendix-configuring-logging
Without a stacktrace, it’s pretty much impossible to diagnose what is causing the timeouts. I would use a file appender and log to a file and set the verbosity to ERROR so we just capture exceptions.
Also, I would stay up to date and use the latest supported client drivers. These can be found either on Nuget or on the “Current Releases” on the left hand column of this page. As of today the latest supported version is https://packages.couchbase.com/clients/net/1.3/Couchbase-Net-Client-1.3.3.zip.
Note that what is on github is not QA verified and is largely a work in progress (towards the net release), so using in a production environment is not suggested.
