[ULTRAMONKEY-USERS] UM3 & High Capacity Highly Availability and Load Balancing problem

[Nathan Brown]

I have 2 load balancers setup running debian and 2 web servers setup running
fedora 7

 

My main problem is that when the load balancers first come up and start
routing traffic everything works fine, I can view ipvsadm and see that it
can see both web servers just fine.  The problem comes about 20 or 30
seconds after the the load balancers starts routing.  What happens is one of
the web servers drops and then a few moments later the other web server
drops and then it adds the fail back 127.0.0.1 to the list being the only
active server.

 

What I cant figure out is why for those first 20 or 30 seconds I can use
everything wonderfully but after that some catastrophe happens.  Is it an
ARP issue with fedora?

 

I was able to use the debian setup for the real servers without a problem,
sysctl.conf took the arp setting without error.  The only other thing that
might throw it I guess would be that my balancers operate on eth0 and the
web servers operate on eth1

 

Let me know if anyone has any suggestions
