Dear all, Thanks for so many responses! To Alex: No there is no screen saver service running at the server, and it is a text based server with no X-Window system installed. To asterr: The server is put at the data center and with no keyboard nor serial console connected, maybe not related to SysReq signal I reported this to my boss last night and we agreed to replace only the cpu and motherboard to have a try. If it is purely a hardware problem, I hope it will get fixed soon!
