Logstash crashes then brings Kibana down with it

Hello elastic community,

I get this error intermittently (now constantly)

Logstash is located to the left hand side of the screen. This error takes up the whole screen and I am not able to go find the beginning of it as it is cut off. The elasticsearch and Kibana is shown to the right. I've looked around for similar errors and I was unsuccessful. I tried to load Kibana but it looks like it crashes while trying to load the error.

If you need any more information, let me know and I'll see what I can provide.

Best,
Jiayo

ES is obviously running out of disk. That might explain why it's behaving erratically, which in turn could affect Kibana.

Next time please don't post screenshots, and make sure you send your application logs into on-disk files instead of relying on the console window's buffer.
