Upgrade Jobs fails for NetScaler when we configure scheduled 2 stage upgrade process from NetScaler Console. The jobs seem to create several subtasks that are failing. It completes upgrade on 1 NetScaler but does not upgrade the second one. This happens after upgrading the NetScaler Console to v14.1 43.50.

The fix is done under the internal bug id NSADM-120068.  The code fix was done for this bug in the version 14.1.47.14+ version. 

Problem Cause

The problem was caused due to multiple task logs commands sent to the NetScaler devices.
