at least twice. Its well possible that earlier cases were  masked by
reboots from other reasons. And it has taken me some time before i
linked particular slow network behaviour to a firewall problem

3/ how stable is the 1 month gestation time?
no certainty on this one.

OK, problem is back. About 3 days more then 1 month.

IPv4 browsing is very slow, IPv6 routing is down. I can no longer ping6 
ipv6.google.com. It gets the  record, but no responses. Not even 
when doing it on the firewall itself.

ip -f inet6 route flush makes no difference. Neither flushing the 
neighbor cache


ifdown / ifup of the external ethernet port makes no difference

rmmod tg3 removed both interfaces (so the driver does indeed handle 
those ports) followed by modprobe tg3 made no difference either.


package firmware-linux-nonfree is current.

stopping aiccu, rmmod sit and tunnel4 and then reloading and restarting 
aiccu did solve it


Next time i will start with restarting aiccu, and not rmmoding the 
related modules


Cheers,


Rudy

Hmm, okay.  That should help narrow it down a lot.

Ping.  Do you still have access to this machine?

Still using it. Its my firewall. Sorry for missing the questions. With 
the combination of top/bottom posting i had missed the bottom part.


Your questions:
1/ always behaved this way
Not certain. I installed it, then there were a number of changes that 
also had impact on the firewall, which caused some reboots (like 
changing to new version of squid3 iso squid2). Strictly not needed to 
reboot, but after major changes i always test whether the sytem comes 
back correctly from reboot. I also had some squeeze kernel updates, 
which do need a reboot.


2/ how many times?
at least twice. Its well possible that earlier cases were  masked by 
reboots from other reasons. And it has taken me some time before i 
linked particular slow network behaviour to a firewall problem


3/ how stable is the 1 month gestation time?
no certainty on this one. After the last time i had confirmation this 
was a firewall problem, and had confirmation for 2x. thinking back the 
timespan between the 2 certain occasions is 3 - 4 weeks. But i did not 
keep a record.


4/ When did it start
Do not know. See above

cheers,


Rudy

Ok.  In case you're wondering where these questions come from: it is
an attempt to find what variable changed to introduce the bug.  If
your system always behaved this way, it would mean something very
different than if it started happening when upgrading from lenny to
squeeze, for example.

I'll leave the rest of the investigation to people more knowledgeable
about networking.  For now, please attach

 - full output from dmesg after a normal boot
 - output from reportbug --template linux-image-$(uname -r), so we
   can get to know your hardware.

Thanks again and sorry for the trouble,
Jonathan
