I did some searching first, apologies if this has been already covered but I couldn't find it. Running Logstash v2.2.2, on Ubuntu 14.04.3 LT, m3.medium in EC2. When I try to stop or restart, I get: Killing logstash (pid 23531) with SIGTERM Waiting logstash (pid 23531) to die... Waiting logstash (pid 23531) to die... Waiting logstash (pid 23531) to die... Waiting logstash (pid 23531) to die... Waiting logstash (pid 23531) to die... logstash stop failed; still running. If it's a restart, I end up with two logstash processes running. Any ideas how to resolve this? Thanks! ---

They've added an option to allow Logstash to receive a `SIGKILL` if it reaches a timeout period. I think depending on the system you are using and how you install Logstash will determine how to add this option. I installed mine through an RPM in CentOS so the file I would edit is `/etc/sysconfig/logstash`. The very last line has a variable named `KILL_ON_STOP_TIMEOUT`. Setting that variable to 1 sets it so that Logstash will receive a `SIGKILL` after a timeout period. You might be able to edit the service file directly to add that value to the variable as well. The only issue with this is that it can result in loss of data just be aware of that. ---

Thanks marke72! That's what I ended up doing. I'd found that option but wasn't sure I wanted to use it. ---
