Hi
Last night during a backup (using amanda from ports to a remote server)
my PC running 2.2 cvsupd up till mar 20th had a problem with the network
interface.
The machine was not contactable via the net but was still running when I
went in to check. These are the errors logged in messages

Mar 22 01:15:00 njl sendbackup[446]: error [dump returned 3, compress
got signal
 13]
Mar 22 01:15:22 njl routed[58]: punt RTM_LOSING without gateway
Mar 22 01:15:46 njl routed[58]: punt RTM_LOSING without gateway
Mar 22 01:17:22 njl last message repeated 2 times
Mar 22 01:23:45 njl last message repeated 5 times

I tried to generate a ping out form it and got this
 more ~root/ping.log 
ping: sendto: No buffer space available
ping: sendto: No buffer space available
ping: sendto: No buffer space available

I killed routed and just to be sure rebuilt it (since it was -static and
recent libc updates were installed without a make world), on starting it
I got
Mar 22 11:33:12 njl routed[3000]: Send bcast sendto(ep0,
163.1.65.255.520): No b
uffer space available

Mar 22 11:33:54 njl routed[3000]: interface ep0 to 163.1.65.100 turned
off

The latter after I tried to ifconfig ep0 down.

It is again fine on a reboot and just to be sure I am running a make
world again.

I could not track down any other info but I will again run amanda dumps
tomorrow. Of the 4 filesystems dumped, 3 completed OK, just the 4th one
(/home) which got a quarter of the way through before the server lost
contact. I have no ideas as yet whether this is an amanda problem or
routed or ep0. I fI can reproduce it I will post more deatils but while
the world is building I thought it worth mentioning in case anyone has
had the same behaviour or any ideas what I can do to track this further.

Amanda was basically pumping dump|gzip via udp to a remote server. I
didn't get this problem for the last full backup a few days ago and no
other machine on the same network has reported any problems at that
time.
