It is at the "notice" severity level.  The code says:

"We didn't get a OPT record in response to a EDNS query." and also says 
"We need to drop/remove the logging here when we have more
experience."

Are you getting this debugging for EDNS-related problems for "every 
request"? Maybe need to realize why.

Maybe you can change the setting in 

from ISC_LOG_NOTICE to ISC_LOG_DEBUG(10) in your ./lib/dns/resolver.c.

Or override the resolver category default in your named.conf.
