Cause

Er was een fout met één fout in de PowerPath-code waarbij het probeert om partitie twee keer toe te voegen met verschillende threads. 

Er zouden in deze situatie geen gevolgen moeten zijn voor de host, maar de stack en het bericht zouden worden weergegeven.

Resolution

De oplossing wordt opgenomen in de PowerPath 6.2 GA-release.
