Alena Prokharchyk resolved CLOUDSTACK-1981. ------------------------------------------- Resolution: Won't Fix It depends on the order the components (Daos, Managers) are being loaded. No reason to test management server functionality till its completely up, as some Daos/Managers may not be loaded yet. > NPE's when accessing Management server while its coming up > ---------------------------------------------------------- > > Key: CLOUDSTACK-1981 > URL: https://issues.apache.org/jira/browse/CLOUDSTACK-1981 > Project: CloudStack > Issue Type: Bug > Security Level: Public(Anyone can view this level - this is the > default.) > Components: Management Server > Affects Versions: 4.2.0 > Reporter: Sailaja Mada > Fix For: 4.2.0 > > > Setup: Advanced Networking Zone with Xen 6.1 > MS: Rhel 6.3 > Steps: > 1.
