> After adding logging when RPC callbacks block the reactor for too long, I see a fair number of logs on the YCSB tablet servers indicating that these two RPC calls have blocked the reactor for anywhere between 100ms and almost a second. This implies they could probably cause deadlocks as well, and definitely impact latency of all other RPCs on the server.
