Hi Peter,

In this case, it is both issues.

Many sites have quotas on $HOME, so the idea is to disable the site if 
we are using more than 5GB of space. This test is a little bit Engage 
specific so maybe we should disable it. You can do that by editing

The file seems to exist on the head node, but not the compute nodes. The 
WN install should be on a shared file system as the purpose is for the 
tools to be available to the jobs.
