Hi, Freshly built cluster-2.03.11 reproducibly freezes as mailman started. The versions are: linux-2.6.27.21 cluster-2.03.11 openais from svn, subrev 1152 version 0.80 LVM2.2.02.44 This is a five node cluster wich was just upgraded from cluster-2.01.00, node by node. All nodes went fine except when the last one, which runs the mailman queue manager was upgraded: after the upgrade as the manager is started, the system freezes completely. No error message in the screen or in the kernel log. The system responds to ping, that's all, but nothing can be done at the console except rebooting. Usually when this node is fenced off, shortly after the fencing node freezes as well. What I could find in the kernel log of this second machine is as follows: Mar 26 23:09:24 lxserv1 kernel: dlm: closing connection to node 1 Mar 26 23:09:25 lxserv1 kernel: GFS: fsid=kfki:home.1: jid=3: Trying to acquire journal lock...
