I have same problems migrating from IcePack to IceGrid.

I have a icebox service previous working with IcePack with out problems whe i try to migrate this service to icegrid my service terminated unexpectly when I try to create a Freeze::Evictor

ServiceI code:

void
Oz::Files::FileServiceI::start(const std::string& name, const
   Ice::CommunicatorPtr& communicator, const Ice::StringSeq& args)
{
	std::cout<<"Try to start FileServiceI"<<std::endl;
	Oz::Files::FileServiceI::_adapter =communicator->createObjectAdapter(name);
	std::cout<<"adapter name: "<<name<<" created ok"<<std::endl;
	
	Oz::Files::FileServiceI::_evictor=Freeze::createEvictor(
	Oz::Files::FileServiceI::_adapter,
	"Files",
	"FilesDB");

	std::cout<<"Evictor created OK"<<std::endl;
        ...............................

Icegrid descripto:

<icegrid>
	<application name="oz-files">
	<node name="saturno">
		<icebox id="FileService"
			exe="/opt/Ice-3.0.0/bin/icebox"
			activation="on-demand">
			<service name="Files" entry="Files:create">
				<adapter name="${service}" endpoints="tcp"/>
				<dbenv name="Files" home="/opt/oz-tpv/DB/Files"/>
				
				<property name="Identity" value="FileServer/FileServer"/>
				<property name="Ice.MessageSizeMax" value="20480"/>
				<property name="Freeze.DbEnv.Files.OldLogsAutoDelete" value="0"/>
				<property name="Freeze.DbEnv.Files.DbPrivate" value="0"/>
			<property name="Freeze.DbEnv.Files.CheckpointPeriod" value="-1"/>
			</service>
		</icebox>
	</node>
	</application>
</icegrid>
