I have two Fedora-based apache webservers making the same SSL PUT/POST calls with php/cURL. One works fine, but with the other the call succeeds but takes a VERY long time to return a response (~10 min). (GETs don't seem affected)

The working server's cURL uses OpenSSL for SSL, while the non-working version uses a later version of cURL that uses NSS for SSL

I know nothing about SSL implementations or their effect on cURL. What would cause such a significant delay in SSL PUT/POST responses?

Any suggestions appreciated- Thanks--
