You probably have nodes going down; if you can keep nodes from failing
things will run much better.  'cman_tool nodes' and /var/log/messages may
give us some idea about the source of node failures, whether they are
spurious, if your largish number of nodes are contributing to the
problems.

Ignore those, they are debug messages that were mistakenly directed to
/var/log/messages.
