AEM: How to stop the Traversal?

Due to the way the indexing happens in AEM 6.0 onwards many a times the queries we fire will result in Traversal and can even bring down the system.

How to diagnose the traversal - look for the below WARN in the error.log
WARN [...] org.apache.jackrabbit.oak.spi.query.Cursors$TraversingCursor Traversed <0000> nodes with filter Filter...

Here's how you can stop:

1. Navigate to the Query Engine Settings on the JMX console http://<host:port>/system/console/jmx
2. Copy the LimitReads onto your notepad. Thereafter, change the LimitReads value to any arbitrary number, say 50000.
3. Once you notice that the logs are back to normal i.e. no traversal in the error.log, change the LimitReads to its original value.
