The above indicates that the upstream LDM is being told by the operating-system 
that the connection was broken: in the first two cases because the TCP layer on 
the downstream host sent a "reset" control-message. In the last case no good 
reason for the disconnection was given.  Given the extensive use of the LDM, it 
seems unlikely that these disconnections are due to it, rather, it seems likely 
that they are due to either the network or the networking layers of the hosts 
in question.  You *might* be able to verify this by switching to a previous 
version of the LDM -- although the autoshifting feature in 6.4 might confuse 
the issue.

Incidentally, the timestamps on the two sets of log messages don't correlate.

Do you have a network administrator to whom you can take this problem?
