Problem: pfSense reboot randomly

[freebeebr]

pfSense randomly is rebooting.
In crash log i have this:
118>32-bit compatibility ldconfig path:
<118>done.
<118>>>> Removing vital flag from php72... failed.
<118>External config loader 1.0 is now starting...

In attach i upload the two files for analyses. The CPU is a AMD FX(tm)-8350 Eight-Core Processor.
The RAM Memory was tested by memtest and everything is ok. Always reboot on microcode part and is randomly (sometimes boot ok, other times not boot).

Looks like a storage or filesystem problem to me. Reboot into single user mode and run fsck -y / no less than 5 times (until it neither finds problems or fixes problems), then reboot and see if it's better.

Though given the nature of the backtrace I'm more inclined to think it's a storage/disk failure or maybe disk controller/cable failure.
