consolue -u stops, gets Connection timed out

 I'm running a fairly large installation with conserver (1100+ console).

 Doing a console -u will print out a bunch of consoles, but at some points, 
stops for a bit and then prints:

console.i386: connect(): 52044@192.168.9.2: Connection timed out

 and then prints out the rest of the consoles.

 192.168.9.2 is our master conserver server.  If 52044 is a process id, there 
is no such process on that host.

 I realize I could probably restart the master processes, but that would 
probably result in a fair number of upset users, so just trying to figure out 
what this error is, how to fix it, and how to avoid having it happen again.

 Thanks.
