    Description

      WriteTimeoutException thrown when LWT concurrency > 1, despite the query duration taking MUCH less than cas_contention_timeout_in_ms.

      Unit test attached, run against a 3 node cluster running 2.1.5.

      If you reduce the threadCount to 1, you never see a WriteTimeoutException. If the WTE is due to not being able to communicate with other nodes, why does the concurrency >1 cause inter-node communication to fail?
