Can't remove cron_restart

[sylc]

What's going wrong?
I cannot seem to be able to remove/cancel a cron_restart property.

How could we reproduce this issue?
I have a processes.json as follow

[
  {
    "script"    : "app.js",
    "args"      : "start-server",
    "name"      : "myapp",
    "exec_mode" : "cluster",
    "instances" : "max",
    "watch"     : false,
   "cron_restart" : "*/5 * * * *",
    "env": {
      "NODE_ENV": "production"
    }
  }
]

If i change cron_restart to another value like "*/10 * * * *" and run

pm2 reload processes.json --update-env --only myapp
pm2 save

the cron pattern is updated as expected in /.pm2/dump.pm2 and the restart happen as expected.

if now i remove the cron_restart property from the processes.json file, and redo,

pm2 reload processes.json --update-env --only myapp
pm2 save

the cron_restart property is still present in /.pm2/dump.pm2 and the app will restart.

Supporting information

PM2 version: `2.4.6`
Node version: `6.10.3`
Linux

My current workaround is to pm2 delete myapp and pm2 reload processes.json --update-env --only myapp

Application configuration environment is state full so yes this is exact, the solution is to totally reset the process environment by doing a pm2 delete ; pm2 reload <process.json>
