Good Morning,
After initiating a scan search, After receiving about 44 pages, I receive numerous exceptions on the server, like so,
[2012-11-27 11:10:27,966][DEBUG][action.search.type ] [Mercator] [3] Failed to execute query phase
org.elasticsearch.search.SearchContextMissingException: No search context found for id [3]

After a few more partial page retrievals, like so,
{"_scroll_id":"c2NhbjsyOzI6UTNYLXBKdmRRZTZjdzV5QTRYbEJfdzs0OllJcy1rOUdxVF9TNzBLNnU3ekVuT2c7MTt0b3RhbF9oaXRzOjEzNzA1Ow==","took":63,"timed_out":false,"_shards":{"total":6,"successful":4,"failed":2,"failures":[{"status":500,"reason":"SearchContextMissingException[No search context found for id [2]]"},{"status":500,"reason":"RemoteTransportException[[Ortelius][inet[/10.100.201.157:9300]][search/phase/scan/scroll]]; nested: SearchContextMissingException[No search context found for id [1]];
With each subsequent retrieval, failure rate increases, eventually to total failure.
Is this due to cluster health? or am I doing something wrong? I noticed the scroll_id sent back from the server grows shorter and short, is that normal?
any help would be greatly appreciated..
