Hi, So I did a few optimization tweaks for one of my servers, and had it running overnight doing some timings just to see how well it was doing while idle. Apparently, Spigot thought it hung up and stopped responding, but from the logs, there's nothing that could indicate this happening beforehand (absolutely nothing going on except Metrics and AdBolt). Here's the stacktrace: http://pastebin.com/MA0uc8Ac I admit, I do not know how to read stacktraces at the moment, but if anyone can point me out to a good starting place to learn about these, that'd be great. Amongst some of the modifications were reducing the timeout-time to 30 seconds and reducing netty-threads to 2 (which I don't think should be an issue if nobody connected during this timeframe...). Thanks in advance.
