Solution

If the number amount of 1 GB hugepages on the system exceeds the supported number of hugepages per platform, then after power cycle or reboot, you may have issues running any command that needs to communicate back to JDM.  The message:

error: Error executing the command in JDM 192.168.1.254

will occur if there is not sufficient memory available. 

It is recommended to not exceed the documented hugepages as specified in the following links:
