Server closed communication device?

I get this on some queries in some namespaces.  For instance, this query:

SELECT TOP 10 SessionId, datediff(s,min(TimeCreated),max(TimeCreated)) as ResponseTime
FROM ens.messageheader
GROUP BY SessionId
ORDER BY ResponseTime DESC

It works fine in HSBUS but in HSREG it throws the error.

Does anyone know what would cause this? Would it log something more useful somewhere?
