Hi Sean,
The error happens when PM2 (the process manager used by visionbox) is unable to read memory and cpu utilization info, the solution is to run this command and recommit your image:
path to npm modules:
npm root -g
The path for recent Visionbox versions is:
/usr/lib/node_modules
Running this command inside your visionbox should fix the problem:
RUN sed -i 's/pidusage(pids, function retPidUsage(err, statistics) {/pidusage(pids, { usePs: true }, function retPidUsage(err, statistics) {/' /usr/lib/node_modules/pm2/lib/God/ActionMethods.js
