Briefly, this error occurs when Elasticsearch is unable to handle the volume of data or requests it’s receiving, causing it to run out of resources. This could be due to insufficient memory, disk space, or network bandwidth. To resolve this issue, you can: 1) Increase the resources available to Elasticsearch, such as adding more RAM or disk space. 2) Optimize your queries to reduce the load on Elasticsearch. 3) Implement a more efficient indexing strategy. 4) Consider sharding your data across multiple nodes to distribute the load.

String passwordPrompt = "[?1h=[?2004hpassword: ";
if (security.keystoreLocation != null) {
assertEquals("[?1h=[?2004hkeystore password: "; readUntil(s -> s.endsWith(": ")));
out.write(security.keystorePassword + "\n");
out.flush();
logger.info("out: {}"; security.keystorePassword);
// Read the newline echoed after the password prompt
assertEquals(""; readLine());
