Error description

  • Due to a timing issue, sometimes APC will lose server
    information, affecting its ability to make placements.  In a
    multicell topology, the APC gets notifications from the cell
    agent.  The purpose of the cell agent is in multicell
    topologies...adding a new cell or removing a
    cell...monitoring
    that activity...and it seems like it may be sending a remove
    cel message to the APC to remove the cell.
