All of Active Directory Lightweight Directory Services's LDAP send queues are full.  This can be caused by
clients that continue to send requests faster than they are processing the
results.  In order to prevent the server from becoming unresponsive as a result
of this condition Active Directory Lightweight Directory Services has closed %1 connections that are not
bound as Administrators.  Active Directory Lightweight Directory Services will continue to close connections
until enough send queue space has been recovered to operate normally.
