There are two possible causes of this, and I suspect both are at work to 
some extent.

The first, which will mostly affect your SKS peers, is the growing 
number of oversized keys that are accumulating on the SKS side of the 
graph and will never reconcile with any modern Hockeypuck (although what 
counts as "oversized" is a local parameter and so varies a bit).

The second (and more concerning IMO) issue is churn, which appears to 
affect to varying degrees any peer relationship involving at least one 
Hockeypuck server. I suspect (but cannot yet prove) that Hockeypuck 
calculates key hashes (which are NOT fingerprints) inconsistently in 
some cases, perhaps due to packet reordering. I don't currently 
understand the code well enough to debug this properly (but perhaps 
somebody else here does?).
