• Addressed an issue that may cause the WSMan Service (WsmSvc) to crash randomly when multiple Windows Remote Management (WinRM) requests are being executed in the WSMan Service.

• Addressed issue that caused backups to fail on Hyper-V clusters with CSV volumes enabled.
• Addressed issue where MPIO did not properly restore service after the check condition "Illegal request, LUN not available (sense codes 05/25/00)" occurs.
