We run a site that delivers large files and has many transfers going at the same time and we have noticed nginx slowing down and causing high iowait times. After running a strace we have seen this stat("/var/www/slavefilestore/8f/1o3VKtKeim", 0x7fffda168490) = -1 ENOENT (No such file or directory) open("/var/www/slave/filestore/8f/1o3VKtKeim", O_RDONLY) = 79 as you can see the stat line is missing a slash. Could this be causing our problems ?
