First, searching through the archives I'm about to say "No".
My goal is to provide NFS service to many FreeBSD clients sharing the exports.
The usage pattern appears to be "many reads and not as much writes".
The deployment might look like the following: a SAN and 2 NFS servers sharing
its LUNs.

I can report even more regression with the most recent version (0409) :(
My 2915 seems to work with RELENG_6_0 only. Not always though. Sometimes I had
to reboot to make it associated. Plus the outgoing traffic problem.
I could only associate several times with older versions of RELENG_6. Well,
Well, the recent commit to CURRENT is much better than the previous patches
against STABLE. It associates in almost 100% of my attempts. I can't run "cvsup

I can associate, but AP just doesn't pass my traffic since some point in
RELENG_6. I

The question was about FreeBSD. Do you know any HA solutions working with it?

Removing the entry manually seems to fix the issue. But I can't ping the CARP

Hello, all.
I'm trying to make CARP working on a 2-Xeon hardware. It worked OK on 5.5, but
not on 6.2.
The result of compiling both
options SMP
device carp
into the kernel makes it crash in 'swi1: net' kernel thread on a random
(usually first) use of the CARP facility.

This change looks right to me, but I'm har

EAGAIN was being returned on blocking sockets when all ports were in
use (just wanted to clear that up; the patch seems to just use
non-blocking sockets as an example, anyway).

P.S. -net is for technical discussions of network code,
just wanted to be able to switch it on without
recompiling a kernel (e.g., while running GENERIC), this obviously
doesn't help.
Just food for thought, I guess. I like it either way :-).

It's initialized in COMMON_START().
Please review the following change, from NetBSD:
In icmp_reflect(): If the packet was not addressed to us and was
received on an interface without an IP address, try to find a
non-loopback AF_INET address to use. If that fails, drop it.
Previously, we used the add
remained.
Now, if I turned off delayed acks on C xor R, the latency spike drops
to ~95 ms. If I turn it off on C *and* R, the latency spike
disappears--hence the "delayed ack problem" part of the subject.
Just for reference, here's what the symptom looks like *with* delayed
acks:
