Description (partial)

Installing server certificates on CMX containing OCSP URI(s) can potentially result in a lengthy install taking roughly 30 minutes.
Two OCSP requests are performed, where each check can take roughly 15 minutes in length before an "Error querying OCSP responder" error is thrown and the install script continues.
