Thanks. Oddly that looks like a totally different incident to the core file we had last time. That seemed to be in a node state transition whereas this is in stable running. The last thing to happen was an IPC connection which indicates that libqb might be possibly involved. I recently identified a bug in libqb that's triggered by using it for multithreaded IPC access, but the only Red Hat software that does that is clvmd and the use pattern in the black box output is not clvmd. So unless you have some custom-written multi-threaded software that uses libcmap extensively (do you?) then I'm none-the-wiser I'm afraid :/ Chrissie _______________________________________________ Users mailing list: Users@clusterlabs.org http://lists.clusterlabs.org/mailman/listinfo/users Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://bugs.clusterlabs.org
