The SearchStax® Frequently Asked Questions page includes the following approved question and answer about our Apache Solr Cloud services.


Search Timeout Alert

A Search Timeout is a Threshold Alert that notifies you by email that your deployment has experienced some number of search timeout errors during a period of some minutes. This creates an Incident in the Managed Solr Dashboard. Most timeout incidents are false alarms that resolve themselves within a few minutes. Some of them, however require remedial action.

System Load is Too High

Search Timeout alerts can result when the system is under heavy stress, as shown by elevated CPU and System Load graphs in Pulse. Check the System Load/CPU graphs to evaluate the load. Also, check the Service Graph to see if there is a spike.

This is often associated with a heavy episode of indexing. If the alerts are associated with indexing events, consider throttling back the flow of /update messages.

This situation can be relieved by performing a rolling restart. Contact SearchStax Support if you need any help there.

Request Volume is Too High

It is possible for a cluster to become too busy handling search events, such as during a holiday spike in traffic. Evaluate if the number of timeouts is decreasing and one should just wait, else open a ticket with SearchStax support.

If Search Timeouts become a persistent or chronic problem, consider adding a node to your cluster. Search requests are resolved in parallel across all available nodes.
