Hi again,

Looks like it's still happening. I had several crashes that didn't
block the server, and some that required it to be restarted.
My current config is:
nginx: nginx version: nginx/1.0.4
nginx: TLS SNI support enabled
nginx: configure arguments: --prefix=/etc/nginx
--conf-path=/etc/nginx/nginx.conf
--error-log-path=/var/log/nginx/error.log
--http-client-body-temp-path=/var/lib/nginx/body
--http-fastcgi-temp-path=/var/lib/nginx/fastcgi
--http-log-path=/var/log/nginx/access.log
--http-proxy-temp-path=/var/lib/nginx/proxy
--http-scgi-temp-path=/var/lib/nginx/scgi
--http-uwsgi-temp-path=/var/lib/nginx/uwsgi
--lock-path=/var/lock/nginx.lock --pid-path=/var/run/nginx.pid
--with-debug --with-http_addition_module --with-http_dav_module
--with-http_flv_module --with-http_geoip_module
--with-http_gzip_static_module --with-http_image_filter_module
--with-http_perl_module --with-http_random_index_module
--with-http_realip_module --with-http_secure_link_module
--with-http_stub_status_module --with-http_ssl_module
--with-http_sub_module --with-http_xslt_module --with-file-aio
--with-ipv6 --with-sha1=/usr/include/openssl
--with-md5=/usr/include/openssl

(most of the extra options aren't used in my configs)

I'll try to downgrade to the latest 8.x version and see if it works.
What else would you suggest to do?
