/**
* This exception is thrown when there is a problem in the underlying network I/O. Non-idempotent requests
* should be retried carefully while retrying idempotent ones is more straight forward.
* Events that trigger this exception are
*
* - The underlying connection to a particular endpoint on the server is closed after the request is dispatched.
* So the outstanding requests in flight are cancelled out. It is not definitive if the operation indeed
* succeeded on the server and the socket error happened while a response was on its way out.
*
* - The request cannot be dispatched to the server's endpoint due to various reasons like downed node,
* request queue limit, particular service failure on the node,... If the failure was due to request queue
* limit, try increasing the value on the system property "com.couchbase.sentRequestQueueLimit". The SDK will
* automatically retry the request based on the retry strategy - Best Effort will retry until maxRequestLifetime
* and Fail Fast will cancel the request immediately.
