Ok, i have another new to this problem. I have unplugged the external BCM5720 card, and now there is only the motherboard BCM5720 + the Intel Pro 1000. I created two LACP trunks with 2 ports (1 for each card). The servers doesn't freeze anymore !! (but there is a problem, motherboard bge1 stay active but doesn't collect and distribute. The switch doesn't agregate the port, this problem was present when the 4 bge ports were on the server).
The next test is to disable motherboard BCM 5720 and retry with the external BCM5720, to see if the same comportment is present. -- Best regards, Loïc BLOT, Engineering UNIX Systems, Security and Networks http://www.unix-experience.fr Le lundi 06 mai 2013 à 14:59 +1000, David Gwynne a écrit : > do you have a real serial console hooked up to the machines? more > specifically, can you break into ddb when the machine breaks and get a trace? > > i use carp on vlans on lacp trunks on top of myx(4) and em(4) "quite a lot" > without trouble, so its likely to be bge(4) if you ask me. unfortunately that > means its my fault or responsibility. > > if you could get a trace to verify, that would be much appreciated. > > cheers, > dlg > > On 05/05/2013, at 4:11 AM, Loïc Blot <loic.b...@unix-experience.fr> wrote: > > > Hello misc. > > On thursay i have upgraded one of our BGP border routers to OpenBSD 5.3, > > and i was pleased to get the BCM5720 working.
