Ubuntu Server Crash

Hello 1 of my 2 servers keeps crashing randomly. the latest uptime of the machine was 17days but it then it suddenly crashes without any warning. This is the log from kern.log http://paste.ubuntu.com/p/wzPhrF9r9g/ I could not see the screen because the computer completely locked up and i had to press the reset button for it to start responding. But the previous times it had crashed there was something about a CPU being stuck and that it had waited for 22s.

Thanks in advance.
