I am attempting to start the cAdvisor container downloaded through the Community Applications monitoring section. I haven't changed any settings for the docker from the default config. I get the following errors in the log:

I checked and my docker image is less then the specified max size (20G).

Could someone help me out here?:)

I installed it over the weekend and found I needed to increase "inotify max_user_watches". If you install the app Tips and Tweaks, there is a simple option in there to increase it from the default (If it doesn't state the default, click on the help button. I think it is 524288). The higher the number, the more ram is going to be consumed. My understanding is the default uses roughly 512MB of ram.

 What number did you increase it to get it to work?  524288 seems to be on the high end already...

I doubled it, but I have a ridiculous amount of ram in my system . I actually searched for a "recommended" value to input, and couldn't find anything. If ram is not quite as plentiful, maybe try adding a 100k at a time until it works....
