I didn't see any problems on my two (very lightly-loaded, about
2.5 messages per minute on average) servers.

But I could reproduce the stale fd's in /prod/<PID_of_clamd>/fd
on my workstation by increasing the load on clamd. Just scanning
inbound mail on the workstaion didn't trigger the error.
But scanning a few hundred (clean, text-only) email messages from
this mailing lingst did.
   cat ~/mail/clamav | formail -s clamdscan -

I didn't try to trigger the error on the two production servers.
