PHP Fatal Error

asv345h

@stephenw10
No, just running nut. I have a server running apcupsd and have pfsense running nut in "remote apcupsd" mode.

I don't use email notifications. However, the "Disable SNMP Notifications" is NOT checked and the config fields are all blank. Should disable be checked?

So, this is the only error of this type that I have seen in my 10+ years of running pfsense and I thought it might be a bug.

stephenw10

It is a bug of some sort. We just need to narrow down where it is. So, yes, try disabling the notifications and see if that stops the error reappearing.

Alright, I post back if error returns. Thanks for the help.

For the error to happen there, an fopen function has to fail to open a file for writing in /tmp/.

It's not clear why, though, since it could be one of several things, including (but not limited to):

/tmp is full
If /tmp is a RAM disk, there may not be sufficient RAM to create a new file in the FS
If /tmp is on an SSD/MMC/HDD, the filesystem holding /tmp has a problem (e.g. UFS and needs fsck run several times, or ZFS and needs a scrub)
If /tmp is on an SSD/MMC/HDD, the disk or controller may have stopped responding to commands (disk or controller physical issue, maybe controller driver issue, etc.)

The problem here is that if it is a disk issue the logs may not be helpful unless you pipe syslog to a remote network host. If there is a problem with the disk it can't log that to the disk when a problem occurs. It might print a message to the console, though, but it depends on what happened.

I've tried a few different ways to see if multiple processes competing to write the same file all at once could trigger this kind of error but so far I haven't had any luck drawing it out.

My hardware is a ng-6100 with pfsense pre-installed. Looks like plenty of space at the moment.

I stream syslog to a remote server and have the logs. I searched for "/tmp" but got no hits. A search for "mmc" only found this: kernel: mmc0: <MMC/SD bus> on sdhci_pci0, but that was 4 days after the exception. Is there another search term I should try?

Mmm, nothing obviously wrong there. Seems like it's unable to write the file for some other reason.

I'm seeing the exact same error from time to time as @asv345h since upgrading to 23.01 . I'm also running an ng-6100 running 23.01 (for info, I have a APC UPS plugged in to a USB port). Everything was fine for a year before the upgrade.

Here is an example:

The timing of the error correlates closely with a gateway event:

I have the same issue on all of my pfSense boxes - after the Upgrade to 23.01

stephenw10

The exact same pair of php errors?

This? https://redmine.pfsense.org/issues/14061

Is there some common config all your installs share?

Any update on this error? I started getting it tonight.

My main drive is defintely not full...

//edit: nevermind... found patch c5faa351c1ef6d4555478a7f50b3a16ece7e0b2a on redmine. Sorry for the thread bump.

Same issue here. Seen this error twice after upgrading to 2.7.0 on July 1st.

I also see references to Nut Package (which is installed).

I applied the patch as referenced above, I'll report back with results.

jacksnack2

I just received this error again this morning. Patch has been applied at last posting date.

stephenw10

What error exactly?

jacksnack2

@stephenw10

Please see the error listed at the top of the post.

stephenw10

But not the error in /etc/inc/notices.inc:101 ?

@stephenw10 This is the error:

@Overlord

Doesn't this look like PHP error after reboot ?

jimp

There is another change I committed a couple weeks ago that might help with that, 596a88fa42f0ac77bd2fc2be87b54457df11f64b but I'm not sure if it applies cleanly on a patched or unpatched release. You can try, though.

But the problem is still someone trying to do a function as a non-privileged user that should be performed by root.

wralb

Thanks @jimp

As mentioned previously, I saw this on my 6100 (with the NUT package and an APC UPS) many times when running 23.01. FYI, I never saw it with 23.05 over several months, but saw it again with 23.05.1 (coinidence?).

Anyway, I just installed all recommended patches plus commit 596a88fa42f0ac77bd2fc2be87b54457df11f64b and will report back if I experience this issue again.
