Crazy Solution: I take out any patch cable and re-inserts it, the problem gets resolved. I reset any switch, the problem gets resolved. I disconnect any uplink cable between the four switches or do a ARP reset thru command line, the problem gets resolved for couple of hours or even days.
This sounds like problems with spanning tree in the network. Do you run STP? Take a look at the topology changes reported by stp. Or one more thing - this could happen because of over-fulling CAM (switching) tables of particular switch. Check if you are not running out of memory somewhere.
