Arp Cache issue

[brian irvin]

We have a RHEL 5 box which requires frequent flushing of arp cache to stay up and running and not create network bottlenecks. Anyone have these issues? we have quite a few servers and have never faced an issue before this one. I thought it might have to do with the switch but the network folks say the switch is clear. Any thoughts??
