We are having serious network problems and we're basically trying to pinpoint the problem.
Our LAN consist of :
2 failover PIX firewalls
2 unmanaged switches
15 Windows 2000 servers
1 BigIP load balancer
2 Load balanced web servers
The problem is that we're getting intermittent network connectivity between the servers.
I have analyzed traffic on a few servers and i'm getting a lot of TCP packets that has to be reassembled. (TCP segment of a reassembled PDU)
I'm also getting the following log entries in our load balancer that sits between the web servers and the other servers.
arp info overwritten for 10.1.88.38 by .....
We're at a point where we really don't know what to do and we have had 7 people working on this for a looooong time now. If anyone knows anything that could help me I would be reaaaly greatful!
