We have configured logstash(using default pipeline configuration). We have just one pipeline running.
When I start logstash I see it has 4 pipeline workers and batch size of 125. I am using IMAP input plugin to process emails from server.
I see that all 4 workers establish connection with IMAP.
I found that when logstash is shutdown only 1 connection is relinquished, the other workers are still keeping the connection.
I want to know how to shutdown other workers?
Thanks in advance.
