    Description

      Steps to reproduce

      1. Created a 6 node kv cluster

      2. Created 2 buckets

      3. Created 10 scopes per bucket and 50 collections per scope

      4. Loaded 5000 items onto each bucket (10 items per collection)

      5. Failed over node 172.23.121.71 and 172.23.96.168 gracefully

      6. Dropped collections during the failover

       

      Many DELETE requests return a 503

      DELETE https://172.23.96.196:18091/pools/default/buckets/bucket1/scopes/_default/collections/collection-12 body:  headers: {'Accept': '*/*', 'Connection': 'close', 'Authorization': u'Basic QWRtaW5pc3RyYXRvcjpwYXNzd29yZA==', 'Content-Type': 'application/x-www-form-urlencoded'} 
       
      		 
      error: 503 reason: {u'_': u'Exceeded retries due to conflicting operations on bucket properties.'} {"errors":{"_":"Exceeded retries due to conflicting operations on bucket properties."}}

      Many such delete requests return the same 503

      $grep "503 87" ns_server.http_access.log

      Also noticing that these 503 responses are only observed with delete collection requests for ephemeral buckets
