Subject changed from PHP error with notices to PHP error when failing to write ``config.cache``
Status changed from New to Incomplete

We need a better idea of how to reproduce this. The backtrace is similar to #14061 but that file referenced here -- "telegraf_pfifgw.php" -- does not exist anywhere in pfSense. Googling suggests it's from a third-party addon from an unofficial repo source for which we cannot be responsible.

If there is a way to reproduce it using only our code in base or our own packages, we can look into it more, but otherwise this should be closed and reported to whoever developed that script.

See: https://forum.netgate.com/topic/180488/crash-report-after-upgrade-to-23-05

In that case after updating the Snort package, though the notice looks to be from NUT.
