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.
