Thanks Stephen, My set up is as follows:
client -> eth2-eth3 -> cisco switch The client is directly connected to eth2 on the bridge, eth3 is directly connected to a cisco switch. The port on the cisco has spanning-tree disabled (with 'spanning-tree bpduguard enable') won't won't allow any bpdu's to or from the port. The cisco or the client don't report any errors or show abnormal stats - the communications just stop. The ports stay link up but no traffic can flow until the server is rebooted. After I enabled STP on the bridge I got the same issue (I had to remove the spanning-tree bpduguard from the switch port as it goes to err-disabled otherwise).

Turn on spanning tree and find out. --
