Empty /data/log folder I have Galaxy Sii s9100 with CM 10.2 (android 4.3)

I am encountering the bug that fill the folder /data/log and display the notfication "Storage space running out"

I can see that the problem is coming from the log folder using DiskUsage (1741Mo)

The problem is I can't succeed to empty this folder, I tried :


DiskUsage (it says that I can't delete log files)
ES Explorer (the folder looks empty)
Dial *#9900# (got an error IHM not valid)


Any other ideas ? Or any ideas why I can't use these methods ?
Automated solutions could involve tasker: Make a job running in intervals (e.g. all 3 hours), with the task to shell-execute rm -rf /data/log/* as root, should keep the folder clean. Tasker has a "run shell" command, where you can tick "use root" – that's what you would need.
