Site spidering fails

I get this message when trying to have site search spidering the page. I’m not sure what it means.

{"error":{"root_cause":[{"type":"validation_exception","reason":"Validation Failed: 1: this action would add [1] total shards, but this cluster currently has [1000]/[1000] maximum shards open;"}],"type":"validation_exception","reason":"Validation Failed: 1: this action would add [1] total shards, but this cluster currently has [1000]/[1000] maximum shards open;"},"status":400}![details|500x500](upload://etww1ZMxsankA1qRQ23G1OIgI2J.png)

hello @david.wandar I’ve seen the message on support as well, we’ll be in touch!
