Abnormally high CPU usage on router

[RexVizsla]

Hey,
after a little research and some tweaks I got everything installed. The router setup went flawlessly except that i cant access the firewall plugin as described here already.
However my router has really high Load average and uses so many resources that I even get packet drops.
Upon further inspection, I could narrow down 3 things:

1. The load average isn't immediately high after reboot. First everything looks fine but then over the next few hours it keeps rising until basically using all my CPU resources.
2. I'm not 100% sure what process causes the issue but i narrowed it down to 2 or 3... Most likely it's "uhttpd". This pops up every few seconds and uses a lot of CPU. But there's also a lot of "internet-outage" processes so that could be an issue as well. And sometimes there are many "sed" processes that disappear shortly after.
3. I turned off everything that could consume resources: all statistics plugins and Adblock. That didn't seem to help at all so it has to be something apart from that.

It would be great if anyone could give me some hints, what the issue could be!

I fixed this by stopping the "internet-outage.sh" script from being launched by editing the 1-minute-script and commenting out the block referring to it.
