Hello Marten,

there may be a long running GEM/ Topaz process logged in to your stone,
which still holds a reference to that object in its local memory and
votes the object down after MFC. Restarting all user sessions before MFC
should then fix the problem. Be aware, that also your dev session runnig
the code Object _objectForOop: 325752577 prior to an MFC could itself be
the reason.
