We had 14 indexers under a pool of 2.3TB license.
We added 6 more indexers before 5 days but forget to add it under license pool and it gets 5 violation warning on all 6 new indexers and it was giving below error as below.
[XXXXXXXXX_indexer15] Streamed search execute failed because Error in 'litsearch' command: Your Splunk license expired or you have exceeded your license limit too many times. Renew your Splunk license by visiting www.splunk.com/store or calling 866.GET.SPLUNK.
So now I have added all new 6 Indexer under the 2.3TB pool from UI but still, the error is not going from search head.
