The Manager.condition (i.e. threading.Condition()) variable is used by Synergy for scheduling the periodic manager's tasks at fixed rate. FairshareManager inherits the same variable from Manager and wrongly uses it for different purposes. The problem is that every time the FairshareManager calls the condition.notifyAll() method, triggers unwittingly the execution of the task() method.

SYNERGY SCHEDULER MANAGER
The Scheduler Manager
Synergy is as a new extensible general purpose management OpenStack service. Its capabilities are implemented by a collection of managers which are specific and independent pluggable tasks, executed periodically or interactively. The managers can interact with each other in a loosely coupled way. The Scheduler Manager provides advanced scheduling (fairshare) capability for OpenStack. In particular it aims to address the resource utilization issues coming from the static allocation model inherent in the Cloud paradigm, by adopting the dynamic partitioning strategy implemented by the advanced batch schedulers.
