title: Azure Container Instance - restarting once in a while for no apparent reason
body: <p>I have a few different containerized web apps running on Azure Container Instance (ACI). I recently noticed that some of these containers just restart with no apparent reason once in a month or so. Since the restarts are on different apps/containers each time, I have no reason to suspect that the apps are crashing.</p>
  <p>The restart policy on all of them are set to &quot;Always&quot;.</p>
  <p>Is it normal or expected for the containers to restart even when there is no app crash? Perhaps when Azure does maintenance on the host machines or maybe a noisy neighbor on the same host causing a pod movement to another host?</p>
  <p>(I am in the process of adding a log analytics workspace so that I can view the logs before the restart. Since the restarts are so infrequent, I wouldn't have any logs to look at for quite some time.)</p>
