PUSH-000359
Poll request for client {} from '{}' failed because no matching client session can be found. The client session might have been closed previously. Poll request will be ignored.
Description
The server has received a poll request for an unknown client session. This might be because the client has been closed by the server, or indicate an incorrectly configured load balancer routing an HTTP connection to a server that was not hosting the session. Consider enabling session-stickiness for HTTP clients.
