what the hell :s

That was the server going down for a reboot.

hlds - Steam dedicate server?

This is the system booting up again.
Those are normal boot messages and information from the kernel. Same for the second part of the logs posted ( not quoted here to save space ).

How much memory is your system using when it gets slow? That's a good point to run top to how much RAM hlds, and other software, is using. Maybe the system is swapping at that point too, which could account for the slowness.

Regards

It has crashed here above.

have a look at var/log/messages

New error messages.From hosting they say its DdoS.
