For anyone else that comes across this. Increasing `druid.processing.numThreads` on both my broker and historical solved this problem but I also needed to grant some additional headspace in `-XX:MaxDirectMemorySize` (about 10% more than what the calculation would suggest). I am now suspecting an issue where the direct memory buffer gets filled and kills the thread unexpectedly. I don't have any evidence of this other than the "channel disconnected" errors went away when I added more MaxDirectMemorySize. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
