[opensuse] Weird behavior opensuse 11.1 - DoSed ?

Hi, last few moths my opensuse 11.1 on AMD 4050e CPU needs hard reboot. I'm running it as a internet gateway, it just don't stops respond. After reboot I see following signs in my messages and firewall log: ^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@ Next is record of starting syslog. Have you anybody mets this problem ? Machine is not loaded to high, it is quite boring :). Memory tests are ok, I think that it could be possible DoS attack. How to be sure ?
