The NS1.domain.com A record is misplaced in the abc.domain.com zone. 
Glue records only apply "downwards", i.e. you can have glue in a parent 
zone for a name that lives in the child zone, but not the other way 
around. This erroneous placement shouldn't have caused the whole zone to 
fail, though, so you still need to look for the original and root cause 
of your problem.

P.S. Please stop using the term "root" to refer to your main domain. 
Properly speaking, that term should only be used to refer to the actual 
"root" (i.e. ".") zone, which is the apex of the entire DNS namespace.
