There are a load of old docker images kicking around on that machine that havne't been cleaned up by the look of it (Also there's a `Sophia" directory in the workspace that's about 7Gb - @sophia-guo is that needed (Not critical that it's deleted since docker is the main issue here, and since your directory is from March it seems fairly recent)

[sxa]

Have ran the cleanup_images function from the machine and there is now 44G free

@sxa that is for test debug with same environment with jenkins builds. I have deleted it. Not realized that it's such big folder.
