I have set up a logstash with redis architecture to handle my logs. The way I have organized it is:

```
logstash ---> redis ---> logstash ---> elasticsearch

```

but the problem that occurred is that after parsing nearly 1.25 million logs a java exception is thrown.  
In my `logstash.err` log file, the exception appears as

```
Exception in thread "<file" java.lang.UnsupportedOperationException
    at java.lang.Thread.stop(Thread.java:869)
    at org.jruby.RubyThread.exceptionRaised(RubyThread.java:1221)
    at org.jruby.internal.runtime.RubyRunnable.run(RubyRunnable.java:112)
    at java.lang.Thread.run(Thread.java:745)

```

I think that this exception might be thrown because of logstash unable to open/close a file. So what can I do to rectify this error? The way that my input configuration is set for my first logstash server to send the logs is:

```
input {
    file {
        start_position => "beginning"
        path => [
            "/var/logstash_logs/child1/nginx/*log*",
            "/var/logstash_logs/child2/nginx/*log*",
            "/var/logstash_logs/child3/nginx/*log*"
        ]
    }
}

```

And the way output is sent is like this:

```
output {
    redis {
        host => "X.X.X.X"
        key => "logstash"
        data_type => "list"
    }
}

```

There are no errors in the logs of logstash server with redis installed. Thanks in advance for your help! 🙂
