Strange Apache logs - very slow loading time (Apache Users)

Hi All,

I need a help. I believe something is wrong. I have recently found a strange information on my apache error.log:

[Sat Apr 13 00:08:32 2013] [error] (110)Connection timed out: proxy: HTTP: attempt to connect to 107.6.106.10:80 (*) failed

root@ip-10-145-204-53:~# tail /var/www/shops/88/logs/error.log

And every second the errors are appearing. Is this some kind of DDos attack? Or the apache is misconfigured?

How can I get rid of this problem?

Thank you very much for any help on this. This is a high priority issue.
