[cisco-voip] Device Pool Updates

Just so you know, we are still on 4.1.3 and CPU is spiking on the
publisher.  I guess I am just curious as to why this is happening,
especially since nothing is associated to these device pools.  Is it the
change to the CM groups that is causing the problem, or would any change
to the device pool cause high CPU?  Is this still common with the newer
versions, such as 6 and 7?  Thanks.

Additionally, "cpu goes to 100% on the server". Do you mean on the 
publisher or on a subscriber?  100% cpu isn't necessarily bad.  Which 
process is consuming the processor?  Any update at all results in work

by SQL (or Informix), Aupair (or dbnotify), and affected processes ccm,

cti, and ctftp.

IMHO 'device pools' are system wide objects and fit into the category
things that should not be approached casually.  Take for example:
