I powered off the VM running Centos 6 and NiFi 1.1.2 with active flows in VMWare vCenter. After the next day, I turned on the VM but can't successfully start NiFI. Below are the logs with errors nifi-app.log: 2017-09-15 11:27:38,038 INFO [main] o.a.nifi.properties.NiFiPropertiesLoader Loaded 122 properties from /opt/nifidev-1.2/nifi-1.1.2/./conf/nifi.properties 2017-09-15 11:27:44,603 INFO [main] o.a.nifi.util.FileBasedVariableRegistry Loaded 78 properties from system properties and environment variables 2017-09-15 11:27:44,604 INFO [main] o.a.nifi.util.FileBasedVariableRegistry Loaded a total of 78 properties.
