Which client would you like to start?> 2
Opening tunnel on port 10000... FAILED

What actions should I take to resolve this?
To offer further background below are a few details about the env. my app is running in:
vmc stats logoff
Using manifest file manifest.yml
Getting stats for logoff... OK
instance cpu memory disk
0 0.1% 74.2K of 2G 63.3M of 2G
vmc env logoff
Using manifest file manifest.yml
Getting env for logoff... OK
vmc services
Getting services... OK
name service version
mysql-service mysql 5.1

Answer 1

This is because you have used all of your allotted 2Gb of RAM. To tunnel to a service, vmc needs to deploy a small Ruby application called Caldecott, this uses 64Mb. So in short, you need to free up 64Mb!
