I found a reference to this on Google:

Which basically says the that payflowpro library is statically linked with OpenSSL 0.9.5, but we are running 0.9.6c.  The PHP folks have this problem too.

This explains why our dev servers didn't crash with this problem--the pfpro module just doesn't get as much stress there as it does on production.

Now, how to fix this?  Not sure, we are trying to get a beta version of the lib from Verisign right now.
