Hi Tony,
Thanks for your kind response. Disabling EDNS due to firewall
misconfiguration, raise any problem to DNS activity.? I mean my users
face any name resolution problesms or ...?
Is there any way that we can show that current disabling EDNS happens by
firewall issue ?
Regards,
Ben

How to check that current bind installation has EDNS enabled or ?
what could be reason behind it?
BIND has EDNS enabled by default. These log messages indicate that BIND is
trying and failing to make EDNS queries. This is usually caused by a
misconfigured firewall between the name server and the rest of the
Internet.
