[Xen-devel] network_alloc_rx_buffers panic

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.
