I tried 2nd method using bsd.rd to update the system but I get an error message 
stating that cannot find OpenBSD/amd64 6.0 sets.

 

Path is correct, I crossed check that.

 

When 6.0 is expected?

 

Regards

Antonis,

 

You need to grab the files from 'snapshots/amd64' instead

of the release directory, e.g. from here:

http://ftp.eu.openbsd.org/pub/OpenBSD/snapshots/amd64/

 

And then either:

 

1) reinstall the system (i'd say it's easier to do that)

 

2) if you have access to the console, put new bsd.rd into /

   and then run "boot /bsd.rd" at the "boot>" prompt

 

3) live update your system like specified here:

http://www.openbsd.org/faq/upgrade59.html#NoInstKern

(copy bsd.mp <http://bsd.mp>  kernel you've downloaded to / and then

follow the "Install new userland" section).  This is not

advised however.

 

After that you'll have to either build new kernel from

the source code or I can send you a binary.

Hello Mike

 

Thank you for your quick response. 

 

The problem is totally random and probably has to do with traffic on the 
interface. Never the less, the problem always produce the problem on xnf0 which 
is one of the Wan interfaces I have and never on xnf1 which is the LAN 
interface or xnf2,3,4 which are also Wan interfaces. The installation I have is 
a Wifi gateway. Wifi devices are connected on a wireless network and get access 
to the internet via OpenBSD Box. Services that OpenBSD has are ISC DHCP, NGINX, 
UNBOUND, SQUID etc.

 

Bellow you can find the traffic graph for that period

 



 

I can try any patch but please send me some more information on how to do that.

 

Regards

Hi Antonis,

 

While your report could have been a bit more detailed (for instance describing 
how did you get into this situation), I'm aware of the generic problem with 
failed interrupt delivery that can be triggered under heavy network load, e.g. 
packet flood.  I'm trying to fix this right now.  I'll be committing some diffs 
to -current, so I'd highly recommend updating to the latest snapshot (right now 
we're in the end of locking down 6.0) if you would like to test patches.

 

Regards,

Mike
