Fixed In Version:	piranha-0.8.5-8.el6	Doc Type:	Bug Fix
Doc Text:	Previously, failure to start a single nanny daemon could terminate all the other nanny daemons. As a result, piranha could stop routing requests to real servers if one service monitor failed. This update adds a new option in the lvs.cf file, "hard_shutdown". The old behavior is retained with the default setting of 1. If a 0 value is set, a single nanny does not kill all nannies but the system needs manual intervention.	Story Points:	---
