The last few days I have been having problems with this bug detailed in this
message board thread:
A patch to the linux kernel is available there:
I am testing if it really works, but it takes a few hours before it fails again.
Steps to Reproduce:
Run a moderately busy bind server with a 2.6.14 kernel, stock or gentoo-sources.
Server stops receiving request on port 53/udp of the used affected ip.
Answer to dns queries.
exerpt from syslog:
Nov 8 04:28:32 hammer named: errno2result.c:109: unexpected error:
Nov 8 04:28:32 hammer named: unable to convert errno to isc_result: 14:
Nov 8 04:28:32 hammer named: UDP client handler shutting down due to
fatal receive error: unexpected error
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
