Expected strings (Capacity and Mounted) not found in df output

I am getting the following alert from hobbit 4.2.0:

 
yellow Fri Jun  8 10:53:36 EDT 2007 - Filesystems NOT ok

&red Expected strings (Capacity and Mounted) not found in df output

 
When I look at the output from the client the df output is missing. This is
happening sporadically. Other times it reports the df output fine.

 
Any ideas.
