Opnsense Crash Logfiles

[Meg]

Hello: I am trying to troubleshoot why my Opnsense keeps crashing. I am not sure which log files to look in to find the cause of the crash. Would someone kindly point me in the right direction?

You will need a swap partition in order to see kernel crashes getting logged.

Check if you have a swap by executing (only a swap on persistent storage will work):

Code Select Expand

swapctl -l

If you mean other kind of software crashes, like services maybe crashing in the background (aka not a kernel crash), then you might take a look at the log files. For example System -> Log Files -> General

I have a swap of the default size durring intall. Which log file would I check for kernal crash. My system restarts sometimes every day or every fer days sometimes twice day since last update. I did a system health check and everything looks good.

It's important the swap is on persistent storage like:

Code Select Expand

Device:       1024-blocks     Used:
/dev/gpt/swapfs   8620216         0

What is your output of the command I gave you earlier?

If there is really a kernel crash happening, and the crash gets logged to the swap partition, after an automatically system restart the kernel crash report should be visible at: System -> Firmware -> Reporter.

If you see "No issues were detected.", there has been no kernel crash. Or the kernel crash was not stored on your swap partition.

This is the output.
Device:       1024-blocks     Used:
/dev/ada0s1b    4194304         0

This was the swap set up during the install of Opnsense.

There was a crash report. I submitted it.

You're not alone. I also have kernel crashes.. https://forum.opnsense.org/index.php?topic=45138.msg225446#msg225446
