An hour ago I upgraded the memory of the server to 16 GB. And the server was not accessible for half an hour between 19:30 and 20:00 EEST, because I accidentally loose the SATA connector of one of the hard drives :-(
After I added a new 8 GB DDR3 module the server started normally. I thought everything is OK and left it, but then I tried to connect and wasn't able. So, I went back to check the server and on the console there were many EXT4 error messages. I had to stop the machine again, check the devices in BIOS. Since one of the hard drives was missing I immediately checked the connectors and solved the problem.
I should have done this upgrade long ago, but until recently I though the memory is enough for all the services running. Anyway, the server has enough memory now.
