In LMS4.2, you may get the
error message "ESC RICS0001:Internal Error,unable to process the collected
data from the device" when your device platform is changed. For example,
when you replace a router and you do the inventory! The reason is that LMS is
not able to find the old index and in consequence, the inventory can't be
gathered successfully.
I reported the issue to
Cisco July 2012 and in November 2012 they created a development case with the
bug ID CSCud15801.
