You may see the following error when running a backup of device config in NCM:

Error “NCM configuration difference failed to complete because required resources could not be allocated.  Please see $SPECROOT/NCM/NCMSERV.OUT for detailed information".”  

Additionally when looking in the NCMSERV.OUT you may see error: 

Failed to allocate array: 21505 x 22365 process memory currently set to: 455M.  To increase memory adjust value of -Xmx parameter in: $SPECROOT/lib/SDPM/partslist/NCMSERV.idb 



Resolution / workaround: 

In order to prevent this error being seen you should do the following: 

1. Modify the -Xmx parameter in: $SPECROOT/lib/SDPM/partslist/NCMSERV.idb to 1350M.

2. Restart processd after this.

3. Retry and you should no longer get this error.
