hi, after upgrading to 9.1-stable, this particular hardware - SunFire X2200,
If you're truly running stable/9, and it's up-to-date, you should have have

(a) the SunFire X2200 (r248858) and (b) the DOWN/UP problem (r250650).

Saw similar things happening over here with different broadcom chipset, and the
above revisions
helped significantly (URLs below):

is toggeling bge1 DOWN/UP every few hours, this port is being used by the ILO.
To check, I upgraded another identical host, and the same problem appears.
What is the last known working revision?
I have no idea, but I have older versions, and ill start from the oldets
(9.1-prerelease), but
it will take time, since it takes hours till it happens.
There are ways you can speed up the replication time. I tend to flood a server
with
TCP while I've heard of it happening under UDP flood too.
Here's a nice way to flood a server with TCP (assuming you have SSH access to
the
system via keys):
sh -c 'while :;do dd if=/dev/urandom of=/dev/stdout bs=1m count=1024 | ssh
HOST2KILL /sbin/md5; done'
Run that about 16 times in separate screen sessions from various other hosts on
your network,
taking care to replace "HOST2KILL" with the hostname or IP of the box with the
SunFire X2200.
Let that run for a while, and then when you think you've had a reset (if you
weren't standing
there watching for one)…
grep 'bge.*DOWN' /var/log/messages
On a system that has booted and stayed up-and-running, there shouldn't be any
messages like this:
bge0: link state changed to DOWN
When you actually get this message (if your experience is like ours), you'll be
down for 90 seconds
while the NIC resets.
However, since you say you have some older 9.1 releases… I'd start by first
trying to bring the
replication time of the problem down by using TCP and/or UDP floods. That way
you'll be able to
test for resolution of the problem as you progress up to stable/9 (where the
problem should be fixed
by the aforementioned SVN revisions -- specific to your hardware).
There
is not correlation with time, since they happend at totaly different times.
I rebooted both hosts at almost the same time.
one host :
uptime: 5:24PM up 6:15, 0 users, load averages: 0.00, 0.00, 0.00
May 24 12:53:52 sf-04 kernel: bge1: link state changed to DOWN
May 24 12:53:55 sf-04 kernel: bge1: link state changed to UP
May 24 15:34:25 sf-04 kernel: bge1: link state changed to DOWN
May 24 15:34:28 sf-04 kernel: bge1: link state changed to UP
and
uptime: 5:24PM up 6:14, 0 users, load averages: 0.00, 0.00, 0.00
May 24 16:30:44 sf-10 kernel: bge1: link state changed to DOWN
May 24 16:30:44 sf-10 kernel: bge1: link state changed to UP
this is not serious, the ilo (ssh) connection is ok, but it's anoying, we have
more
than 10 of this hosts, and if I upgrade all of them, the logs will fill up
with this :-)
any ideas?
Well, you say the connection is OK… so it doesn't sound like a full reset as it
was in our case (we have a different chipset).
But I agree that a log full of those would be annoying.
Try getting up to stable/9 in its current state (note: stable/8 also has all the
aforementioned revisions too).
