Patch fa24b46 resolving this issue has been committed in cluster.git http://git.fedorahosted.org/git/?p=cluster.git;a=commitdiff;h=fa24b460c51aa0c47d0842703feea8bca0ed66b7 Essentially, the dlm was trying to create a configfs entry for a node with no address. This lead to a NULL pointer being dereferenced and the dlm crashing. The above mentioned patch now checks for a valid address before continuing.
Sorry, set the wrong status.
