Hi Rishi, Do you really need soft-commit every second? Can you make it 10 mins, for example?
What is happening (conditional on checking your logs) is that several commits (looks like 2 in your case) are arriving in a quick succession. Then system is starting to warmup the searchers, one per each commit. This is a waste of resources, because only one searcher will be used in the end, so one of them is warming in vain. Just rethink your commit strategy with regards to the update frequency and warming up time to avoid issues with this in the future.
