Hi While doing bulk request to elasticsearch ,we are observing to many daemon thread. Which are Elasticsearch Timer daemon thread. How we can stop or kill these and free the memory? For every bulk request it generating a single daemon thread. ---

Because of these threads, out of memory error is coming. So I want to free the memory.And also when these daemon thread is created there must be some way to stop them ---

You have a memory issue may be but that's not probably the way to solve it. Better to understand what configuration you have, what you are doing with the cluster... ---

Hi, I am getting following error java.lang.OutOfMemoryError: unable to create new native thread 11:15:43 at java.lang.Thread.start0(Native Method) 11:15:43 at java.lang.Thread.start(Thread.java:717) 11:15:43 at java.util.concurrent.ThreadPoolExecutor.addWorker(ThreadPoolExecutor.java:950) 11:15:43 at java.util.concurrent.ThreadPoolExecutor.processWorkerExit(ThreadPoolExecutor.java:1018) 11:15:43 at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1160) 11:15:43 at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) 11:15:43 at java.lang.Thread.run(Thread.java:748) And while monitoring there are 1800+ daemon threads, So I am thinking that is somehow I can remove these thread to solve this error. ---

What version of Elasticsearch? How are you observing these threads? How are you counting threads? Can you provide a list of all threads and their names in your Elasticsearch process (use jstack)? ---
