hi there

I run logstash as a service in window server.  
I use tcp input, grok filter, amazon\_es output in my logstash config.  
I stream .net application logs using Log4netSocketAppender to logstash host.

strange thing is that restart logstash service then... no more logs come to logstash.

then i copy and replace Log4netSocketAppender.dll in app.

very strange, logs come back to logstash

I try like 3 times, it's same 😃

`may i know why Log4netSocketAppender.dll doesn't work whenever logstash service restart??????`

i m running logstash v6.1.1.

This sounds like a problem on the sending side, i.e. not a Logstash problem.
