I found the same issues after extensive usage with Crypt::SSLeay.  My
limited testing with sites that allowed both HTTP and HTTPS led me to
believe that Crypt::SSLeay is not thread safe.  When I looked into
this about two years ago, my suspicion was that it was SSLeay itself,
not the Perl wrapper code.  I basically gave up on trying to find a
solution and it's been forever since I have thought about this
problem, so I don't know that I can provide much more detail.

At least it's not just you!
