Hi Chris,

But how would it cause an outage? ROOT##003 would not necessarily be
copied from the file ROOT##001.war

It'll be a separate deployment, but just using the same build that got
deployed as ROOT##001.

Whether ROOT##001 is marked for undeployment should not make a
difference to ROOT##003. They will "own" different sessions.
