Thank you for your answer.
As it turned out, after the 4th reboot they emailed me
that a fan is not working correctly and they are
replacing it. Since then it works fine.

Unfortunately, I can't install chkrootkit because of
this error (which I get when trying to "make" most of
the programs):

[root@ns chkrootkit-0.35]# make sense
gcc -DHAVE_LASTLOG_H   -o chklastlog chklastlog.c
In file included from /usr/include/signal.h:300,
                 from chklastlog.c:41:
/usr/include/bits/sigcontext.h:28: asm/sigcontext.h:
No such file or directory
make: *** [chklastlog] Error 1

I'm checking for a system attack the commands from
knowledgebase, which didn't pointed out any attack.

And for cat /proc/meminfo I'm getting this, which I
guess is normal:

Thanks again,
