We're using the Java transport client. The problem only happens when the app is dealing with a high number of requests. I wondered whether it was because the client takes a little bit of time to detect that the node is unavailable: potentially up to 10 seconds in total (with default settings - 5 seconds to ping the node, another 5 for the timeout).
And perhaps even after the node has been dropped the existing connections to the node still need to timeout (not sure what the default is here)?
