RHEL 6 BIND 9.8.2 SRV Record CNAME Problem

My RHEL 6 BIND 9.8.2 is already updated to its latest 9.8.2-47-8.3 version.

The BIND is a recursion server that serve client requests.

I facing the problem that when I do a query for a SRV record that points to a CNAME, it fail with lameserver FORMERR error.

It seems whenever the SRV record is pointing to a CNAME, it returns SERVFAIL, however, if the SRV points to a A record, it's successful.

I tried to set the check-integrity no but seems no effect.

Is there any patch/update available to have the BIND not failing for SRV record point to CNAME???

It seems BIND 9.9.7 does the job, but RHEL 6 most updated BIND is 9.8.2.

Thanks for any advise.
