node.js stdout/stderr stops being logged to nginx error.log after logrotate

[NeoPhi]

We have a daily logrotation configuration that sends a kill -USR1 to nginx after rotating the log files. If a node.js application is logging to stdout or stderr messages are not written to the new log file unless nginx is restarted.

That's because sending SIGUSR1 to Nginx only makes Nginx reopen it logs. You also need to tell Passenger to reopen the logs. You can do that by running passenger-config reopen-logs.

Thank you, I missed that in the release notes.
