    Could be alot of things.

    First on my mind would be a communication error between the two nodes.
    Sometimes that would affect clcomd's ability to send information for discovery, or verify from one node
    to the other.

    clcomd is built to be robust in case of individual connections between the two nodes in the clusters.
    To do that, it may communicate on any ip address that is configured for HA.

    So, if you have an odd route, or some other configuration problem...It is possible for clcomd to fail
    intermittently but the other parts of the cluster work just fine.

    But it is hard to tell from a description. Usually the quickest way to solve the problem is through reviewing
    a snap -e. And the quickest person to do that is your local friendly IBM support person. :)

    Hope this helps,
    Casey
