Shibboleth and database connection leak

[Cantor, Scott]

> I've investigated this a bit further. Shibboleth reports a deadlock:

No, it's the database refusing to take locks properly to serialize the transaction. All our code supports retry logic based on driver error codes, as documented.

I have no idea what any of that has to do with a leak, that's a bug in one of those libraries or a meaningless message.
