Question about "too many records"

[J Doe]

Hi,

I run my own validating recursive resolver with BIND 9.18.28.

In the resolver logs I noticed:


     01-Aug-2024 10:30:22.294 query-errors: info: client @0xec879280280
         127.0.0.1#14435 (bf10x.hubspotemail.net): query failed (too many
         records) for bf10x.hubspotemail.net/IN/A at query.c:7842


The client in this case was my mail server software.  What does "query
failed (too many records) ..." mean ?

Is this BIND saying that the client (the mail server software),
requested too many records or that the result of the query yielded too
many records or something else ?

Thanks,

- J
