High CPU Usage - appDemo process

Hi. I recently replaced a FGT 200E (running 5.6.x) with a FGT 201F (6.2.x) where I lightly modified the configuration.
The new firewall (201F running 6.2.7) now shows high cpu usage on one alternating core. 
CLI and diagnose sys top shows
Run Time: 0 days, 12 hours and 39 minutes
3U, 0N, 9S, 88I, 0WA, 0HI, 0SI, 0ST; 7979T, 3990F
appDemo 169 S < 99.8 0.8
 
So in other words the process appDemo uses 99,8% cpu. 
 
I've tried to identify the appDemo process and the purpose of it without luck. It's not listed here: https://kb.fortinet.com/kb/documentLink.do?externalID=FD40822
 
Any clues on how to process further here?
 
Thanks.
