There are 9 instances wrting to 1TB of SSD disk space.
Other 3 are writing to SATA drives, and have autosoftcommit disabled.

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

You are correct, but once a second is REALLY often. If the rest of your
config
And in addition, if you begin to see more onDeckSearchers warming up
simultaneously, just bumping up maxWarmingSearchers is only postponing the
proper core problem solution [1]
We have been through this ourselves!

Shawn,

My index size is pretty small ~4GB and its running on a SSD drive with ~100
GB space on it.
Now I see the warn message every 15 seconds.
The caches I think are minimal
All,
I am running SOLR Cloud 4.6, everything looks ok, except for this warn message
constantly in the logs.
