Subject Re: Re: [users@httpd] Apache 2.2.16
Date Fri, 06 Aug 2010 15:30:31 GMT
For Apache 2.2.15, I've used the two different versions of OpenSSL 0.9.8n/0.9.8o, the latter
version of OpenSSL was used ever since it was released and I had no issues. I've used different
versions of OpenSSL (when they became available) with different versions of Apache, still
never encountered any of these issues before.

Your suggestion was my next step, just wanted to see if anyone has experienced these issues.

Thanks for the quick response!
