Hello. We've run into some trouble in attempting to bring a 64bit windows machine into an existing cluster. The cluster has (had) two 64bit linux members and was running fine when we attempted to merge a 64bit windows machine into the group. Anytime the windows machine wrote on a node, the node was thereafter unreadable by either of the original members. Exceptions of the following form were thrown by the other members. All machines were using 32bit java. Has anyone seen anything similar? Have I missed something fundamental about 64bit windows? Thanks in advance for any help or insight.
