Hi Mark, I am am also facing the same issue when trying to index in SolrCloud using DIH running on a non-leader server. The DIH server is creating around 10k threads and then OOM cannot create thread error.
Do you know when or which version this issue will be solved. I think a workaround for this issue is to find the leader from zookeeper and run the DIH on the leader.
