On Tue Oct 27, 2015, history.state.gov began buckling under load, intermittently issuing 500 errors. Nginx's error log was sprinkled with the following errors:

2015/10/27 21:48:36 [crit] 2475#0: accept4() failed (24: Too many open files) 2015/10/27 21:48:36 [alert] 2475#0: *7163915 socket() failed (24: Too many open files) while connecting to upstream...

An article at http://www.cyberciti.biz/faq/linux-unix-nginx-too-many-open-files/ provided directions that mostly worked. Below are the steps we followed. The steps that diverged from the article's directions are marked with an *.

1. • Instead of using su to run ulimit on the nginx account, use ps aux | grep nginx to locate nginx's process IDs. Then query each process's file handle limits using cat /proc/pid/limits (where pid is the process id retrieved from ps). (Note: sudo may be necessary on your system for the cat command here, depending on your system.)
2. Added fs.file-max = 70000 to /etc/sysctl.conf
3. Added `nginx soft nofile 1

Method 2

This only really works if you don't mind losing any other keys (than your own).

Export public and secret key and ownertrust

gpg -a --export chris@seagul.co.uk > chrisroos-public-gpg.key
gpg -a --export-secret-keys chris@seagul.co.uk > chrisroos-secret-gpg.key
gpg --export-ownertrust > chrisroos-ownertrust-gpg.txt
