ASA 5550 8.4.3 show cpu usage - error

One of our firewalls  - Cisco ASA 5550 8.4.3  - has got a problem. Our monitoring system requests the cpu usage on the box and from time to time we got an error. It was now possible to catch the error message - the output of show cpu usage looks like on the attached picture.

We did not found something in the know bugs neither in the "Resolved Caveats in ASA Version 8.4(4.1) ".

Anybode the same problem?

Kind Regards

Klaus
