I am running netview 5.1 on aix 4.2.1.  I realize that this should be
upgraded.  The system has been working fine, but recently approximately
every 21 minutes all of the nodes enter the down state, and then 2 mins
later it comes back up.    It's rather annoying, I am now trying to figure
out if it's a netview anomoly or if something is wrong with the tcp/ip
stack.  During this time, telnet sessions are extremely sluggish and my snmp
scripts (gets/walks/sets..) timeout also.   
        Has anyone else had this occur?  What causes it and or fixes for it?

Thanks
