Several people have reported issues with IIS and Resin servers (or maybe SSL terminators sitting in front of those servers) that are fixed by downgrading OpenSSL. The AESNI performance improvements were nice but stability is more important. Downgrade OpenSSL from 1.0.1e to 1.0.0f. Fixes #5360 (and others).
