Novell ZENworks 7 Desktop Management Support Pack 1 - ZDM7 SP1 Desktop Management


NAL works fine prior to update, after putting agent in place for ZDM7sp1 IR3a HP1 or HP2, NAL now crashes on workstations.  This is a fairly rare anomaly as certain applications seem to cause this issue due to memory management.


To obtain a hot patch with the fix for this problem, follow the instructions in KB 3484245 "Updates to Novell ZENworks 7 Desktop Management" which can be found at

Additional Information

The memory allocation handles for ZEN needed to be changed to work properly with large Windows environment variables. Prior to the change, the code would use the same allocation of memory size for the reply packet as the request.  Since it was unknown what size the reply packet would be, in some cases not enough memory was allocated.  This caused a heap corruption issue in rare instances and NAL would crash.
