can't attempt attribute query, either no NameID or no metadata to use

[Mailvaganam, Hari]

Hi List:

A very high Shibboleth authentication traffic SP has been noticing messages such as below on all 8 of the load balance server nodes (each with an SP):

2013-10-29 21:14:34 WARN Shibboleth.AttributeResolver.Query [273358]: can't attempt attribute query, either no NameID or no metadata to use

The above message occurs periodically.

The integration is direct SP-to-IdP SAML2 (no EDS or WAYF).

Any ideas on where to look? Filesystem/SAN seem fine (problems do not correlate to the SP message timeline).

I have checked the mail-list archives – so fare none of those seem to fit but will keep digging.

Thanks.
