I did some more research. I don't think I find something useful. I'm attaching pcap files from each interface when Ethernet broadcast is working and the it stop to work. You can see arp who has messages, they also stop to work around 14:18:24.
I think the whole problem is because of 00:e0:4c:4c:40:91 machine which sends arp who-has every two seconds, if I unplug this machine from switch everything is working fine (I'm not able to break the bridge). If someone is interested in more details about this strange bug please contact me off the list. On Fri, Aug 06, 2010 at 01:34:05AM +0100, Mikolaj Kucharski wrote: > No, sorry, false alarm.
