Running 6.2.4 We are getting this error in one of our dashboards.

rejected execution of org.elasticsearch.common.util.concurrent.TimedRunnable@55490381 on QueueResizingEsThreadPoolExecutor[name = es-01/search, queue capacity = 1000, min queue capacity = 1000, max queue capacity = 1000, frame size = 2000, targeted response rate = 1s, task execution EWMA = 27.3ms, adjustment amount = 50, org.elasticsearch.common.util.concurrent.QueueResizingEsThreadPoolExecutor@450c7b3f[Running, pool size = 10, active threads = 10, queued tasks = 1392, completed tasks = 805972]]

What is the way to increase the queue capacity? We cannot add more nodes at the moment.
