This error is usually a symptom of a problem, not the actual problem.

Either you are running into performance issues that are making your
commits slow, or you are committing too frequently.   Either way, you've
got a situation where one commit (with opensearcher=true) is not able to
finish before the next commit starts.

Solr puts a limit on the number of searcher objects that can be starting
up (warming) at the same time. You've exceeded that limit. Here's a wiki
page about slow commits:

The rest of that wiki page discusses other things that can cause Solr
performance issues.
