Briefly, this error occurs when Elasticsearch receives a response for a request that has already timed out. This could be due to network latency, slow processing, or heavy load on the Elasticsearch cluster. To resolve this issue, you can increase the request timeout limit, optimize your queries for better performance, or scale your Elasticsearch cluster to handle more load. Additionally, ensure your network connectivity is stable and fast enough to handle the data transfer within the timeout limit.
This guide will help you check for common problems that cause the log ” Received response for a request that has timed out; sent [{}/{}ms] ago; timed out [{}/{}ms] ago; ” to appear. To understand the issues related to this log, read the explanation below about the following Elasticsearch concepts: response, request.
Log Context
Log “Received response for a request that has timed out; sent [{}/{}ms] ago; timed out [{}/{}ms] ago; ” classname is TransportService.java.
We extracted the following from Elasticsearch source code for those seeking an in-depth context :
TimeoutInfoHolder timeoutInfoHolder = timeoutInfoHandlers.remove(requestId);
if (timeoutInfoHolder != null) {
long time = threadPool.relativeTimeInMillis();
long sentMs = time - timeoutInfoHolder.sentTime();
long timedOutMs = time - timeoutInfoHolder.timeoutTime();
logger.warn("Received response for a request that has timed out; sent [{}/{}ms] ago; timed out [{}/{}ms] ago; " +
"action [{}]; node [{}]; id [{}]";
TimeValue.timeValueMillis(sentMs); sentMs;
TimeValue.timeValueMillis(timedOutMs); timedOutMs;
timeoutInfoHolder.action(); timeoutInfoHolder.node(); requestId);
action = timeoutInfoHolder.action();
