As I began to run the server for the newest update, the server would take roughly 1 minute to "Prepare the starting region." After finally starting, the server would constantly repeat "[WARNING] Can't keep up! Did the system time change, or is the server overloaded?" as well as get unbelievable amounts of lag, somewhere around 786ms. It also, because of the lag, will not allow me to connect to the server, giving me a "Read time out" error, as well as freezing up the server with even more lag. I tried restarting the server multiple times getting the same errors.
