After running two domUs for a week, I'm seeing a lot of messages like this: xen_shm_unmap: callback xen_shm_unmap: callback cleared xen_shm_unmap: callback xen_shm_unmap: callback cleared xen_shm_map: ENOMEM xen_shm_unmap: callback xen_shm_map: ENOMEM xen_shm_map: ENOMEM1 Can we put those messages conditionally? (ifdef DEBUG or whatever). Thanks.
