nginx server over https using up all available file handles
- by mmr
Hi all,
So I have an nginx server that's working over https with Sinatra. When I try to download a jnlp file in a configuration that works fine over Mongrel and http (no s), the nginx server fails to serve the file with a 504 error. Subsequent checking of the logs states that this error is due to overflowing the available number of file handles, ie, "24: too many open files". Running
sudo lsof -p <nginx worker pid>
gets me a huge list of files, all looking like:
nginx 1771 nobody 11u IPv4 10867997 0t0 TCP localhost:44704->localhost:https (ESTABLISHED)
nginx 1771 nobody 12u IPv4 10868113 0t0 TCP localhost:https->localhost:44704 (ESTABLISHED)
nginx 1771 nobody 13u IPv4 10868114 0t0 TCP localhost:44705->localhost:https (ESTABLISHED)
nginx 1771 nobody 14u IPv4 10868191 0t0 TCP localhost:https->localhost:44705 (ESTABLISHED)
nginx 1771 nobody 15u IPv4 10868192 0t0 TCP localhost:44706->localhost:https (ESTABLISHED)
nginx 1771 nobody 16u IPv4 10868255 0t0 TCP localhost:https->localhost:44706 (ESTABLISHED)
nginx 1771 nobody 17u IPv4 10868256 0t0 TCP localhost:44707->localhost:https (ESTABLISHED)
nginx 1771 nobody 18u IPv4 10868330 0t0 TCP localhost:https->localhost:44707 (ESTABLISHED)
nginx 1771 nobody 19u IPv4 10868331 0t0 TCP localhost:44708->localhost:https (ESTABLISHED)
nginx 1771 nobody 20u IPv4 10868434 0t0 TCP localhost:https->localhost:44708 (ESTABLISHED)
Increasing the number of files that can be opened is no help, because then nginx just blows right past that limit. And no wonder, it looks like it's in some kind of loop to pull all available files.
Any idea what's going on, and how to fix it?
