Hi @bobdenotter I did as you recommended, and increase PHP memory_limit to 256MB and when running bin/console c:c it does it without problems now.

I noticed this post come up in Slack, I am wondering if this is related, when I clear the cache using Bolt's backend I get this:

// Clearing the cache for the dev environment with debug                       
 // true                                                                        

00:03:43 DEBUG     [php] Warning: file(/proc/mounts): failed to open stream: No such file or directory

    }
  }
]

 [OK] Cache for the "dev" environment (debug=true) was successfully cleared.

@eduardomart Not sure if it's related.. Sounds like a restrction in the server setup.. Does it work otherwise, if you ignore the warning?
