Hi, We rebooted one machine is our cluster (which uses cman) and we got the following message on the changelog of all of the other machines of the cluster (and they panicked!)... We are using a snapshot of the STABLE branch from May 9, 2006. It seems strange to panic the kernel for a ENOMEM... from syslog: Error queueing request to port 1: -12 kernel: Kernel panic - not syncing: membership stopped responding -- Olivier Crête ocrete@xxxxxxxxx Maximum Throughput Inc. -- Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
