Re: EsRejectedExecutionException: rejected execution (queue capacity 1000)
unbounded queue for threadpool, isn't changes such as unbounded will exhaust system resources? It could either exhaust system resources due to each thread use specific amount of system resources, thus render the system not stable or if the system has file descriptor set, probably via ulimit, that number of processes per user hit the limit?
