The OpenSSL Dev mailing-list has just discussed a fix for an OpenSSL
deadlock, with a thread trying to re-acquire an already-held lock, as a
rare occurrence; changelogged as "Fix possible deadlock when decoding
public keys".  The report I read was a report from the OpenLDAP folks.

Perhaps you're hitting the same issue?  Does that patch help?
