Hi all,

anyone knows what could be the reason that this message appears on the log of our juniper M20?

I think this is usually an overcrowded CPU usage on the Routing-engine.

Check the CPU load:

Show chassis routing-engine

show system processes summary

or

show system processes extensive

someone sees something unusual?

Thanks for your reply

I recommend that you test the hard drive with a SmartD test. You must run the below commands as root and start the test: root@router> request chassis routing-engine hard-disk-test long disk /dev/ad1 or root@router% smartd -oe /dev/ad1 < --- This will enable the test. root@router% smartd -oX /dev/ad1 < ---- will run the extensive test Show results: root@router> request chassis routing-engine hard-disk-test show-status disk /dev/ad1 or root@router% smartd -oa /dev/ad1 Smartd commands can take over 20 minutes to finish, but will not be service affecting, which means it can be run in production.
