That's really strange, changes between 1.0.12 and 1.0.14 are
minimal. Could you please re-try with 1.0.12 to see if it works
for you without problems?

I'm mostly concerned by local changes by your OS vendor, not about
openssl 0.9.8e by itself. BTW, when you've upgraded your openssl
last time? I.e. did the same openssl package version worked for
you before, or you've upgraded it with nginx as well?

As already suggested - you may build nginx with any particular
openssl version statically, by using --with-openssl= configure
