I switched to BCM5700 some day ago and it seems to have fixed the
problem, thought I'm still waiting some day to be really sure.

Sorry... not anymore... now the servers are in production...
Indeed, some week ago, I've posted two links to jpegs showing some part
of the kernel dump that may be useful... (grabbed throught ERA).

It may seem more related to a particular usage than on the load. I have
5 almost identical machines, three of them are really identical, same hw
configuration, same OS (redhat 8) and one of those three happened to
crash pretty frequently while others one or two times, not more.
The software running on those three machines is the same (they are three
DAoC servers) but the one crashing has a service more than the others.
