This is not a feature request, this is a FATAL BUG. @mikeprimm

Turned off the watchdog and let run for 15 minutes, no change. Also set debug on and received no other log messages from Dynmap in either debug.log or latest.log. Able to start the server without Dynmap added, please let me know what I can do to help troubleshoot.
