Policy error with OS 10.9 client and JSS 9.21

[dmw3]

having updated to JSS 9.21 we are getting the following error messages show up in the jamf.log on a test OS 10.9 client, anyone seen something similar or is this new with this combo?

Things are A-OK for me with 10.9 and 9.21. The only "Unknown" errors I see are semi-random recon errors.

Did you ever find a resolution to this? We are having the exact same problem with 9.32 and 10.9.4 which started last Wed apropos of nothing.
