Problem with disk space

Stop the process that is doing it.

A guy drops off his car to the mechanic after hours and leaves a note…. "Car intermittently not working properly"…

Anyways, I think I found the problem. Though access/error logs were not on in my nginx server, it took almost 90% space of my total disk. I don't know why, cause I didn't turn on access logs.

Few hints would have been nice. Thanks anyways.

You need to give us something more to work with than: "My disk space is filling with something suspicious pretty quickly."
