Could not find thread (Ticker WS)

Some random tickers are being completely unresponsive. Certain symbols (that vary) return an empty queue for about a minute.

Wondering whether this has anything to do with it

Hey @kariya2 ,
Thanks for submitting this issue!
Without the source code it's a bit hard to debug, but it could be possible that the threads you're looking are dead, instead of unresponsive (perhaps the code crashed?)
