Hi Maxim, thank you so much for your feedback. Last I talked to Dflook he was having trouble getting the backtrace and core dump due to compilation problems. He is going to keep trying.
I just ran this per your request:
[root@lb01 ~]# /usr/local/nginx/sbin/nginx -V
nginx version: nginx/0.8.36
built by gcc 4.1.2 20080704 (Red Hat 4.1.2-46)

configure arguments: --with-http_ssl_module --with-http_stub_status_module --http-log-path=/usr/local/www/logs/access.log --error-log-path=/usr/local/www/logs/error.log --with-debug
