stephan added on 2012-08-29 09:18:23 UTC: How many checkins does that repo have?

in content_get (rid=1606416160, pBlob=0x7fff5fbff720) at content_.c:275

that rid seems extremely high and (coincidentally???) the high bits match the masks being passed in the client_sync() call. The rids are sequentially-generated, which implies that either this repo has over a billion artifacts or that there is an overflow/underflow happening somewhere.
