We're currently haveing an issue with one of our nginx servers. It's using an extreme amount of disk I/O.
It's the / (root - cciss/c0d0) partition that's being abused.
See picture of iotop here: http://imgdrp.com/MziB
nginx is installed in /usr/local/nginx
Logging has been disabled (as far as i can see (cant find any logs being written to and i believe that all has been disabled in the conf files))
The files nginx servs (php files) is located on another harddrives/partition.
What is it that are creating this I/O? How can i find out which files / commands that are creating the I/O
Looking forward to hearing from you.
