Description nuitari 2005-11-08 21:21:59 UTC

The last few days I have been having problems with this bug detailed in this
message board thread:

http://www.gossamer-threads.com/lists/linux/kernel/583359?page=last

A patch to the linux kernel is available there:
http://bugzilla.kernel.org/show_bug.cgi?id=5505

I am testing if it really works, but it takes a few hours before it fails again.

Reproducible: Always
Steps to Reproduce:
Run a moderately busy bind server with a 2.6.14 kernel, stock or gentoo-sources.
Actual Results:  
Server stops receiving request on port 53/udp of the used affected ip.

Expected Results:  
Answer to dns queries.

exerpt from syslog:

Nov  8 04:28:32 hammer named[11721]: errno2result.c:109: unexpected error:
Nov  8 04:28:32 hammer named[11721]: unable to convert errno to isc_result: 14:
Bad address
Nov  8 04:28:32 hammer named[11721]: UDP client handler shutting down due to
fatal receive error: unexpected error

Comment 1 nuitari 2005-11-09 21:11:42 UTC

The bind server that had this issue is now running stable for a whole day. This
is more then twice the time that was happenning before.

The patch applied cleanly to gentoo-sources.

Forgot to close. This was fixed in 2.6.14-r1
