How can I stop it or is it normal Thanks
Looks like normal bots trying to abuse your apache.. Most likely your apache is already patched and protected against such exploits. (Buffer overflow, malformed packages etc) Normal background noise on the net. Just ignore it for now... worst case simply block IP by firewall.
