Subject [users@httpd] Core dump happens with Apache 2.2.15 using openssl 0.9.8n
Date Thu, 20 Jan 2011 11:47:48 GMT
Hi All,

Below issue i am facing:
Core dump happens with Apache 2.2.15. Problem is happening under stress
condition of normal http requests along with the additional condition of
insecure client renegotiation requests generated. For insecure client
renegotiation requests, "SSLInsecureRenegotiation" option is already set in
the apache configuration.

Following is the core trace:

We need to know whether this is a known issue with Apache 2.2.15 with
openssl 0.9.8n  and any workaround available for this.

Your prompt response is highly appreciated.
Thanks in advance.

Matty
