Can you make sure this is not a hardware memory error by running an  
extensive memory test on the machine\>

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

–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?  
Its gonna be hard to figure out the culprit since you’ve lots of 3rd  
party modules 🙂
