I have a Debian Wheezy vps on the cloud.  Today I tried to login using the VNC console provided by my vps service provider but everytime I login the server automatically reboots after 5 seconds! Has anything similar happened to you? How can you troubleshoot a problem like this in 5 seconds? Is this the result of a hack or what do you think is causing this? Any help is greatly appreciated
