Firewall has rebooted without any strange log entry

[Sessa45]

Hi Guys!

I saw in the logs that apparently there was a reboot some time ago. But I could not see in the logs why it was.

You can see how pfBlockerNG performed its cronjobs. So far so good. And then you can see how all of a sudden it was logged, which kernel is used for booting.

I can not currently explain why the pfSense is restarted.
Could someone help me with that :)?

Thank you very much!

Try to run a memtest86 - might be a RAM Problem ...

[Sessa45]

Thanks for the answer.
I first checked the memory in the terminal and checked it with the information in the WebGUI.
There seems to be something not quite round, right?

The WebGUI shows me a relatively low usage. In the terminal but a very high value.

Or do I understand the output in the terminal wrong?
Installed are 4 GB of RAM.

I would like to first test as much as possible without running the memtest, since the pfSense is not available as long as the test is running.

This isnt a real Problem its only that BIOS and operating system reports available memory in different ways.

Unfortunately a comprehensive RAM-test without rebooting the machine isnt possible. Maybe you can find a time when the machine is not so much needed ...

On the other hand that suddently reboot could also be generated by a power spike/failure from the power supply.

Thank you for your reply.

I have some (3) APU boards running on it with the pfSense. All 3, however, show me a problem related to the pfBlocker.
Since apparently the RAM can not be allocated, it could possibly be a fundamental problem with the pfSense.

There were error(s) loading the rules: /tmp/rules.debug:29: cannot define table pfB_NAmerica_v4: Cannot allocate memory - The line in question reads [29]: table <pfB_NAmerica_v4> persist file "/var/db/aliastables/pfB_NAmerica_v4.txt"

Something strange. I currently have no idea why these problems occur.
Someone an idea? :)

You said it yourself : probably :

Cannot allocate memory

But what does it mean?

I have more than enough memory (4 GB) i only use pfBlockerNG.

Try to raise in the Advanced Configuration Options the Firewall Maximum Table Entries!

Very true.
But PHP, when executing the 'PHP' script, doesn't reserve that much memory for the session.it executes.
That will be far less.
See the php.ini, the "memory_limit"
Look at https://your-pfsense.tld/phpinfo.php to see what your php settings are - and you find your value.
That's the value that got depleted.

I can not found such a tunable configuration. Could you please tell me where i can find this option?

I only received a nginx 404 error :)

404 error

Euuhh ... Oops !

Let me introduce you into this marvelous world of being a 'programmer' ;)

First lesson :

This is the file

<?php
phpinfo();
?>

Call it "phpinfo.php"

Place it in here /usr/local/www/

You first php script program ^^
