            The first issue is that you are using pokemon exception handling, you really don't want to catch them all.

            Catch specific exceptions, only, or at least only catch Exception and make sure to re-raise asyncio.CancelledError (you don't want to block task cancellations), and log or print the exceptions that are raised so you can further clean up your handler. As a quick fix, I replaced your try:... except: continue blocks with:

            This has to do with the fact that scrapy-redis uses its own scheduler class which serializes/deserializes all requests through redis before pushing them further to the downloader (it keeps a queue on redis). There is no "easy" way around this as it's basically the core scrapy-redis functionality. My advise is to not put too much runtime sensitive stuff into meta as this even generally not the best idea in scrapy.
