At night, the CPU load drops, then grows again. while the traffic does not drop

What is server kur?
Do you have ecc memory? if not, have you tested it recently?
Do you have video acceleration available?
Is your database in an ssd?

So not ECC. Just to be sure, I'd run a test like memtest86 a couple passes.

Just a shot in the dark but how are your CPU core temperatures in the daytime? Is it throttling due to heat during the day but then cooling off at night?

It's not about temperature.

Here is the monthly schedule. After rebooting the server, the cpu became under 100, before that it worked by half.

it's all about memory. He returned what was standing, the CPU load returned to normal 40-50%. I put a new one, cpu 100%.

the problem was solved by replacing the memory with 2 * R7416G2133U2S-U
CPU usage is back to 40-50%
