I actually saw the same 01sysctl script in there yesterday and thought it was causing a soft reboot when I gave sysctl controls to Rom Toolbox Pro. Not sure if that was the cause or if I should have deleted it, but the reboots stopped immediately lol.
I had been using 3 different apps to run CoD tweaks so when I centralized them all in Rom Toolbox Pro, I thought maybe the sysctl app I had been using had left that script and was causing a conflict. I also admit I don't know wtf I'm talking about so correct me if I'm wrong but it DID stop the reboot haha.
Interesting...could have been the case with Sysctl Config app leaving the script behind...not to sure either. I too was using 3 different apps to run CoD tweaks as well and centralized them using System Tuner Pro (I liked the GUI and what it had to offer)...outside of Sysctl Config for what it does, which is not found in the STP app.
