Lately I am suffering from "random" freezing of the server that goes black and does not respond. The clients stop working (It is mounted a ldap, it is a Lliurex server). The last thing that happens in the log before "exploding" is the following code:

I do not know why this happens, and I have not touched anything since it was always good, until now. The version of lliurex is 16.04 (The last LTS).

EDIT 0: It has frozen again without any sense, I look at 8:40 all went well and after a while, around 9:00 it was frozen, it did not answer anything, nor keyboard or mouse.

EDIT 1: My current processor is "AMD Ryzen 3 1200 Quad-Core Processor", 8GB RAM, and GT218 graphics [GeForce 210].

I would follow this procedure:

The ip that appears would block it with iptables. Meanwhile, it would also update the OS. If you have active samba, if you can deactivate it. Leave the server with the minimum services, and go activating them as time passes without falls.

If it keeps falling, then go up the verbose of the samba / ldap log until you get the problem.

These problems are usually fixed with the update. If you fix it by blocking the ip, go see what soft and version of it is "attacking" to look for incompatibilities.
