Hello, I'm using the repository-s3 plugin and after using it for some months I now cannot get the list of snapshots: ``` curl elasticsearch:9200/_snapshot/long_term/_all {"error":{"root_cause":[{"type":"remote_transport_exception","reason":"[SVVyQPF][10.127.1.203:9300][cluster:admin/snapshot/get]"}],"type":"null_pointer_exception","reason":null},"status":500} ``` Elasticsearch logs this: ``` [2017-07-25T12:01:47,038][WARN][r.suppressed] path: /_snapshot/long_term/_all, params: {repository=long_term, snapshot=_all} org.elasticsearch.transport.RemoteTransportException: [SVVyQPF][10.127.1.203:9300][cluster:admin/snapshot/get] Caused by: java.lang.NullPointerException ``` I use curator to take the backups and after grabbing backups successfully it fails when it tries to delete old snapshots because that's when it requires a list too: ``` 2017-07-25 11:53:02,191 ERROR Failed to complete action: delete_snapshots. : Unable to get snapshot information from repository: long_term. Error: TransportError(500, 'null_pointer_exception', '[SVVyQPF][10.127.1.203:9300][cluster:admin/snapshot/get]') ``` I have a feeling this is due to some kind of timeout. I turned on debug logging and while I couldn't find a more specific reason this fails I noticed it made ~ 2K requests to S3 until it failed and it stopped at 90 seconds. Is this a configurable timeout? Please help! I got no access to my backups! ---

That sounds very bad. I think you should open an issue in elasticsearch. Can you tell more about your version? ---

Just upgraded to 5.5.0. ---

And it appeared just after the upgrade? ---

Nope it started a few days before so it started while on 5.4.1.`curl`ing for the list of snapshots took increasingly long in the past but it still worked. Eventually I reached a curator timeout which I increased and it was working again. Now it seems to be breaking before it hits that timeout. ---

I see. AFAIK we don't set any 90s timeout when we are using the AWS SDK and defaults don't seem to set that as per [http://docs.aws.amazon.com/sdk-for-java/v1/developer-guide/section-client-configuration.html](http://docs.aws.amazon.com/sdk-for-java/v1/developer-guide/section-client-configuration.html). We are just setting the setSocketTimeout which is by default `50s`. > And AFAIK it only set the timeout for a single API call. May be it's a more global timeout that we have in snapshot/restore? @Igor_Motov Do you have an idea? ---

Can you check logs on `10.127.1.203` around `2017-07-25T12:01:47` to see if there are any other messages there? ---

Added some more logs to the issue [https://github.com/elastic/elasticsearch/issues/25878#issuecomment-317748498](https://github.com/elastic/elasticsearch/issues/25878#issuecomment-317748498). Regarding the time I am providing logs from a request initiated at `2017-07-25T12:26:30` because that's when I had DEBUG on. ---
