title: Why do my google cloud compute instances always unexpectedly restart?
body: <p>Help! Help! Help!</p>
  
  <p>It is really annoying and I almost cannot bear it anymore! I'm using google cloud compute engine instances but they often unexpectedly restart without any notification in advance. The restart of instances seems to happen randomly and I have no idea what's going wrong there! I'm pretty sure that the instances are been occupied (usage of CPUs > 50% and all GPUs are in use) when restart happens. Could anyone please tell me how to solve this problem? Thanks in advance!</p>
