Core dump happens with Apache 2.2.15 using openssl 0.9.8n

[matty roland <matty.roland1@xxxxxxxxx>]

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.
