Overall, the thing which upset me the most is that the software crashes. C++ library.
Would it be because I am running so many bots? Is there a limit to the maximum number to run simultaneously?
It has nothing to do with number of bots.
I do see it more often when Polo is fucking up, though. I think the bot isn't handling something properly when Polo is wonky. I don't know if it messes up on other exchanges.
It did this error for me on Bittrex a number of times, up to the point that I couldn't open the Bittrex market at all. It was clearly a weird API response from Bittrex (I could see in the logs that it wasn't JSON at all).
So it seems to me that some improvement of error handling would be required here. Normally, leonArdo should be able to continue past the unintelligible API response, and not simply crash wioth that C++ Library error instead.
