Infrequent exception in Asp.net 2.0 application

    When posting back data I get the following exception:
    "Validation of ViewState MAC failed. If this application is hosted by a
    Web Farm or cluster, ensure that <machinekey> configuration specifies
    the same validationkey and validation algorithm. Autogenerate cannot be
    used in a cluster."

    The exception occurs at random when posting back data. We are not using
    a web farm or a cluster.
