Nifi version 1.9.0.3.4.1.1-4   of my 3 node cluster we have one server that tends to get an excessive amount of timeout errors. If this node is ever master/coordinator data processing is very slow. If the nifi service is restarted while this node is master/coordinator this server starts back up with unable to create native thread. This only happens with 1 node on my cluster and all other nodes work as intended.   This setup has worked for months with no issues. Only change made was reverted back. That change was to round robin load balance. That node is showing low utilization. We are just lost and any help is greatly appericated.  last note we have senstive data flowing through this cluster so getting full logs are not easy for us.
