Description

SYMPTOMS
  • My /var partition overflowed, causing havoc.
  • Found a huge /log/nginx/error.log with many weeks of data

ANALYSIS AND IMPACT

This log file is essentially an invisible time bomb for pfSense admins:
  • It is invisible in the UI
  • It is not specifically configured in the nginx conf file (uses default /var/log/nginx/error.log)
  • It is not referenced nor cleared by any log rotation
  • Status -> System Logs -> Settings -> Reset Log Files does not clear this log
    (Thus, NOT true in docs: "Pressing this button will clear log data from all of the logs managed by the pfSense base system.")
  • It is not cleared on reboot

IOW, this error.log grows ad nauseum until pfSense dies. :(

I'm running 2.4.4p2

In the meantime, a real killer ;)

Half-baked workaround: add an earlyshellcmd of

 rm /var/log/nginx/error.log

This is easily accomplished with the shellcmd pkg
Only effective on reboot but better than nothing.

(Does #8350 rearchitect so this error log is visible to the administrator? If so, good going, Jim :) )

For the vast majority of users, the nginx log does not contain much of anything. I'd look into what you've got going on there. But do so on the forum. This is not a site for that kind of discussion.
