Q: Can Bugzero be deployed in a clustering environment?

A: The Standard Edition does not support clustering by default and it may not work
   properly in a cluster/clustering environment. In particular, if admin loggs on from
   multiple places and updates the project configuration, then, the project will
   no longer be in sync. You must keep only one instance of Bugzero running. 

   A new add-on feature can be used to enable clustering.
