I changed the power adapter.
I checked the voltage in electrical power.
But he reboot ?

That low free memory is suspicious.

Have you installed dude or any additional packages on it?? Have you enabled DNS cache and increased cache memory?

Memory is constantly changing

Try to make a supout.rif file, or check if there is an autosupout.rif file in the Files folder. Send those files to support and we can check what is going on there.

Overheating?

Already sent supout file support@mikrotik.com

What does this show?

I had this problem once. We had a faulty hardware due to bad POE adapter, have you checked it? Check temps, voltage, etc. And of course: supout.rif to Mikrotik’s staff.

I was having the exact same issue with the same hardware.

The RB750Gr3 was working fine for 13days and then started randomly rebooting.
Interestingly enough I had a second RB750Gr3 with virtually the same config with the only difference that the primary internet uplink was a PPPoE Client on the RB which rebooted randomly.

I didn’t solve the issue itself but made my desired config work with a workaround.

The issue occured with 6.38.5 and 6.39.1.
