Hi guys, The subject is explicit enough :). It happened quite often.. Here's a link from the monitor, sorry I don't have any kernel dump at the moment: http://www.sebastien-han.fr/images/ceph-kernel-crash.jpg It happened on 2 different servers running Ubuntu 12.04 with 3.2 for the first one and 3.5 for the second. Every node runs 0.48.1 Any insight will be appreciated :) Cheers! -- 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
