I woke up to my site being down this morning. I called the tech guys and they told me my system partition was full, here is what they said.
There were symlinks for /usr and /var that were pointing to themselves, which I deleted, but your / directory if still showing to be 100% full. You need to log into your machine via ssh and this data that has been generated and filled this directory. For us to perform any further work, it will incur administrative charges.
I understand that these things are going to happen and I will have to pay but I haven't the slightest idea of what a symlink is and why they are pointing to themselves. They are currently working on it but I am wondering if there is something in my threads that may be causing that, I would like to prevent it in the future.
