The following errors were found which prevent this node starting server.conf: java.lang.NullPointerException Node beta_service_01 sanity failed. See server log for detail. PPM failed the pre-startup sanity checks and will not start
I checked the log file and it was not updated with any error
So far what I have noticed happening in my environment when I get the sanity failed usually is because there is still some processes running and one of the nodes has not shut down completely, have you checked the windows processes to see if Java.exe is still running?
