How do I go about removing the child domain so that I can re-create the. I cannot add a new DC to the domain because it has no active servers to verify with. I have a child domain that has no active DCs, the servers that the DCs were on have been deleted. But if you don't log locally but instead configure SIEM, such possible shortage of disk space may take more time to happen. Depending on config, the logs may be cleared by your reboot. Peter mentioned already the tool df which might provide a hint if logging or what else will create a lack of disk space. I further recommend to look into its logging config. That's reported in the head section of the output. You should not only look what is consuming currently most of resources but also to which extent that server is already swapping memory. I want to complement to look further onto output of top. Sudo reboot looks more like a work around instead of troubleshooting.

I am just wondering how I can trouble shoot this I therefore has to log in via putty and do a sudo reboot and then when it comes back up it seems to be fine. Corresponds to what others have called ssh (on different platform) with different UI.
