I also have a core dump file. Do you need it? Also, are you mounting the ceph file system on the same node as the osd? This might be a sync(2)-induced deadlock. Putting a ceph fs mount on the same node as an osd is dicey in low memory situations. On older glibcs and kernels without syncfs(2) support, it can easily deadlock. sage -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
