Sorry, for the multiple edits - was losing characters.

I'm investigating this now but it may have to do with the PollingXHR.Create's Task.Run never finishing until it runs out of threads and then finally craps out due to exceptions. I think this is due to if incoming messages (data) continuously calling OnData, which then recurses back into a new Poll and a new Task.Run.

I'm thinking that Polling._onData should not initiate another Poll, but instead just finish with parsing.

To recreate this issue, use PollingXHR only and then send socket information from the server every 500ms-1000ms indefinitely. The client will continue to recurse into a new Poll via the _onData function - not allowing the initial PollingXHR.Create's Task.Run to complete. Eventually, due to stack overflow/memory issues, Create's will fail into the general exception try/catch.
