how to resolve the boot issue of Palo Alto firewall

I have seen a couple of times of PA200 stuck during booting, the status light is amber and all the interface won't work except mgt and console. when you console in the box you might can see the auto-commit is fail and keep trying. the error message could be unknown application "zoom" or anything else

"Error: Undefined application 'zoom'
(Module: device)
Commit failed
Failed to commit policy to device

"

here are the steps I did to resolve this:

1. delete the content cache
    delete content cache curr-content version 90000 type all
2. rebuild the content database
   debug swm rebuild-content-db
3. install the content file
   request content upgrade install force yes file xxxxx.xx
