Getting Error || unable to convert errno to isc_result

[Lightner, Jeff]

On RHEL the kernel doesn't change within the main release (RHEL6) in this case will always be 2.6.32-xxxxxx and RHEL does the support including back porting bug and security fixes into their extended release (which isn't the same as the base kernel).   They do the same thing for the BIND release they support within the main RHEL release.

To go to a 3.x kernel one would have to go to RHEL7 but that isn't necessary given the way RedHat does support.

Hello

What uncle Google found for me:

http://www.bind9.net/BIND-FAQ

Quote:

"Q:
Why do I get the following errors:

general: errno2result.c:109: unexpected error:
general: unable to convert errno to isc_result: 14: Bad address
client: UDP client handler shutting down due to fatal receive error: 
unexpected error

A:
This is the result of a Linux kernel bug.
See: http://marc.theaimsgroup.com/?l=linux-netdev&m=113081708031466&w=2"

Kernel 2.6.32 end of support date was 6/1/2014, and if I am not mistaken, Bind 9.8 is not supported anymore either (only branches 9.9 and 9.10)

I don't want to bother you with obvious answers, but IMO you should consider upgrading to supported versions of both your OS and BIND, since there were some serious security issues reported and patched lately and your vulnerable system may be at a risk.

Maybe ISC people will have some solution for you, but generally, people are encouraged to keep up with the supported versions.
