[Condor-users] Can't find WANT_SUSPEND in internal ClassAd

["David A. Kotz" <dkotz@xxxxxxxxxxxxx>]

I'm running 6.7.20 on Ubuntu Dapper, and one node keeps generating the 
following error.  I've seen it a few times on other nodes, but mostly on 
the one node, which shares a local config with around 60 other machines. 
 Any idea what is causing this?
