when I flood my server with ApacheBench, with a concurrency of 1000 I expect most of my queries to be backlogged since I have raised backlog to 8192 by setting nginx listen backlog to that value and also raising the relevant Linux kernel parameters to support this limit.
Now the behavior I actually get is that I will get alot of stat() "" failed (24: ) in my error log, with the "some file" part actually being a file checked for by a rewrite rule. I get this for pretty much every file that the rewrite rules check for.
Should I change other parameters? My maximum FD (limits.conf) is raised to 65536, as well as the kernel parameter fs.file-max.
Is this a bug with nginx?
I'm running nginx 0.7.50 on Ubuntu Hardy LTS with lots of 4GB of RAM and Quad Core CPU.
Any help appreciacted.
