My set up is as follows:

client -> eth2-eth3 -> cisco switch

The client is directly connected to eth2 on the bridge, eth3 is directly co= nnected to a cisco switch.  The port on the cisco has spanning-tree di= sabled (with ‘spanning-tree bpduguard enable’) won’t won&= #8217;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 com= munications 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 ot= herwise).

Kind regards,

Mark

You might also be creating a packet loop?
Turn on spanning tree and find out.
