I ran into a odd thing running a split command.
I have a tmpfs with 14gb of allocated size. I have 16gb of ram
I have a single 6gb file on HDD which I attempted to split into 200M chunks into my tmpfs
split ~/Downloads/RAW.tar.bz2.gpg -db 200M image_
Logically, 6gb of split files should not overwhelm a 14gb tmpfs.
The first time I ran it though, I think the whole X display server crashed. It restarted and brought me back.
Of course, I had to try that again.
So I ran it again and this time it killed my firefox process (using ~1gb of ram), then the time after that it killed banshee.
I thought tmpfs prevented you from using more space then possible & crashing other programs?
