Under my user a hidden system folder
.cache/upstart/ is getting insanely large - 99G. This is mainly due to a file
gnome-session.log. Does anybody know what this folder is and why it may get so large? Can I safely remove the file?
I had this problem also, gnome-session-Unity.log file was getting large.
Before this I installed the scratch programming environment, this programm has the squeak-vm dependencies also installed 1st time on this machine. The squeak-vm was locked on the launcher, the line in the gnome-session-Unity log file
this entry was repeated and the file getting bigger.
Also a window from squeak-vm was opened and couldn't normally close that window.
In order to solve the problem I uninstalled the scratch package and the squeak-vm package, close the window from squeak-vm with xkill.
Environment: Ubuntu 14.04 , scratch 220.127.116.11~dfsg1-5, squeak-vm 1:18.104.22.16814-1ubuntu2, zenity 3.8.0-1ubuntu1
