Issue/Introduction
After upgrading Spectrum NCM is experiencing issues:
SPC-OCC-10747: Error capturing configuration for host: NCM configuration difference failed to complete because required resources could not be allocated. Please see $SPECROOT/NCM/NCMSERV.OUT for detailed information.
Next knowledge document has been implemented, without success:

To workaround the problem it is needed to restart the NCM Process via processd, which is time consuming
Here is an Output from the NCMSERV.OUT as it happens.

Failed to allocate array: 41003 x 40989 process memory currently set to: 3641M. To increase memory adjust value of -Xmx parameter in: $SPECROOT/lib/SDPM/partslist/NCMSERV.idb, 'processd' will need to be restarted after making this change.

Environment
Release : 21.2.x, 22,2,x
Component : Spectrum Applications
Cause
The upgrade installer revert some configuration files, like $SPECROOT/NCM/config.xml, to its default values.
There is a configuration entry in this file to allow the diffs and large captures. By default this value is set to off, which might cause the behavior reported in this knowledge document.
<diff-largefile type = "java.lang.String" >off</diff-largefile>
Resolution
1. Edit the file $SPECROOT/NCM/config.xml
2. Change this entry from:
<diff-largefile type = "java.lang.String" >off</diff-largefile>
to
<diff-largefile type = "java.lang.String" >on</diff-largefile>
3. Kill the NCMService process. Processd will automatically start it back up
