I just spun this up in our environment, and it works perfectly for a while. I know this may be reaching, but I am wondering if you guys could help me out with an issue. It seems, at random, it will freeze the entire system. When it freezes, it also takes out the internet for all things connected to the same switch as the box doing the elastic stack. Once i turn off the box the network springs back to life....no idea what is going on. the last line in the logs that I can see before it dies is " Feb 2 11:05:50 ubuntu kibana[1042]: {"type":"response","@timestamp":"2018-02-02T16:05:47Z","tags":[],"pid":1042,"method":"post","statusCode":200,"req":{"url":"/elasticsearch/\_msearch","method":"post","headers":{"connection":"upgrade","host":"172.28.146.66","content-length":"6150","user-agent":"Mozilla/5.0 (X11; Linux x86\_64; rv:57.0) Gecko/20100101 Firefox/57.0","accept":"application/json, text/plain, /","accept-language":"en-US,en;q=0.5","accept-encoding":"gzip, deflate","referer":"[http://172.28.146.66/app/kibana","content-type":"application/x-ndjson","kbn-version":"6.1.3"},"remoteAddress":"127.0.0.1","userAgent":"127.0.0.1","referer":"http://172.28.146.66/app/kibana"},"res":{"statusCode":200,"responseTime":3151,"contentLength":9},"message":"POST](http://172.28.146.66/app/kibana%22,%22content-type%22:%22application/x-ndjson%22,%22kbn-version%22:%226.1.3%22%7D,%22remoteAddress%22:%22127.0.0.1%22,%22userAgent%22:%22127.0.0.1%22,%22referer%22:%22http://172.28.146.66/app/kibana%22%7D,%22res%22:%7B%22statusCode%22:200,%22responseTime%22:3151,%22contentLength%22:9%7D,%22message%22:%22POST) /elasticsearch/\_msearch 200 3151ms - 9.0B"}" Apologies, am new to all things ELK ---

This is unlikely something that the Elastic Stack is doing, and what you are seeing is a side effect. > [@Vantine82](#): > > When it freezes, it also takes out the internet for all things connected to the same switch as the box doing the elastic stack Are you sure it's not something on the switch? ---

Changed jack locations twice and set up new switch just to make sure of that. It is set up to where I only have the ELK box and a test box (just to test internet). When the ELK box freezes, no internet for the test box, power it down, net is back to normal. Is there a log that would perhaps be more helpful? Thank you!! ---

Is there anything in the system logs? ---
