Some users are hitting this panic in network_alloc_rx_buffers()
when running a big network intensive app:
    /* Check return status of HYPERVISOR_dom_mem_op(). */
   if ( rx_mcl[nr_pfns].args[5] != nr_pfns )
	        panic("Unable to reduce memory reservation\n");

I'm not clear on what is happening here.   Are the domains changing size?
Which memory reservation is being reduced, xen0 or xenU?
All the domains are v2.6.8.1, changeset 1.1331 from  Tuesday.

David
