title: Sitecore 9.1 Azure master index rebuild gets stuck
body: <p>I'm working on a Sitecore PaaS solution on Azure. I provision a Sitecore xsmall instance with the standard marketplace procedure. Right after installing I went for a complete index rebuild. But when Sitecore starts rebuilding master database indexes, it gets stuck after a random number of indexes are added.</p>

  <p>I tried a number of different configuration modifications but none of them worked. </p>
  
  <p>Any ideas?</p>
  
  <p><strong>[EDIT]</strong></p>
  
  <p>Ok, I found the logs.</p>
  
  <p>Nested Exception</p>
  
  <blockquote>
    <p>Exception:
    Sitecore.ContentSearch.Azure.Http.Exceptions.AzureSearchServiceRESTCallException
    Message: {"error":{"code":"","message":"The request is invalid.
    Details: definition : Invalid index: The index contains 1036 field(s).
    An index can have at most 1000 fields.\r\n"}}</p>

  <p>I saw there's a patch for Sitecore 8 but I'm using v9. Can I install it anyways?</p>
