weird problem.

every now and then I see these errors in the logs, and the arp tables in my
cisco router get hosed.  clearing the arp table fixes the problem, but I
would like to prevent this from happening.  Are there any guidence,
experience, or ideas with this problem.


my setup is the following.
3 servers. using spread, wackamole, and backhand.

netravis1# cat /env/lvWeb/spread-3.16/conf/spread.conf 

#MINIMAL REQUIRED FILE

Spread_Segment  225.0.1.1:4803 {

        netravis1               192.168.2.191
        netravis2               192.168.2.192
        netravis3               192.168.2.193
}

# Spread options

DebugFlags = { GROUPS PRINT EXIT }

EventLogFile = testlog.out

EventTimeStamp = "[%a %d %b %Y %H:%M:%S]"

DangerousMonitor = false
