Hi,
I recently ran a query for searching 4 million records. My heapsize was only 1 GB and so I got an out of memory exception. I ran the query several times just to make sure. Later I decided to increase the heap size. But no matter how many times I exitted the terminal I am unable to stop the elasticsearch process, which was not the case before. I am still able to execute the curl command to contact the elasticsearch server, even though the ps command shows that neither java not elasticsearch is running. Also if I try to start the elasticsearch process anyway with increased heapsize, I get the following error : Out of memory could not create native threads. Any advice would be great. Thanks.

Did you try a ps -ef command to see running process and find the PID number?
Then kill -9 that process?

Hi dadoonet thanks for the idea. I later tried a ps -aux and realized that
there were several instances of java vm running inspite of the reboots and
logouts. I forcibly removed them and was able to stop the elasticsearch
process. Thank you very much.
