"resource limit"

[a k'wala]

Symptom: In Ubuntu 13.10, 'apt-get update' has started showing several
warnings like the following, even though the keys are present:
W: GPG error: http://us.archive.ubuntu.com saucy Release: The following
signatures couldn't be verified because the public key is not available:
NO_PUBKEY 40976EAF437D05B5 NO_PUBKEY 3B4FE6ACC0B21F32

'apt-key list' begins with the following:
gpg: keyblock resource
`/etc/apt/trusted.gpg.d//webupd8team-y-ppa-manager.gpg': resource limit

I am thinking this might have to do with gnupg because the only mention of
this that I could find was from 2002, when gnupg went from 1.0.6 to
1.0.7<http://www.gossamer-threads.com/lists/gnupg/users/9230>.
What does the "resource limit" message mean? Should I run 'gpg
--rebuild-keydb-caches' as suggested in the GnuPG 1.0.7 release
announcement<https://lists.gnu.org/archive/html/info-gnu/2002-04/msg00013.html>
?
