gwled using high amounts of CPU on APU2
-
I'm having a problem with the gwled package. It seems that after a while, the CPU just keeps increasing.
I noticed that it’s using massive amounts of CPU, pushing the load average well above 20. Even disabling doesn’t fix it, only removing the package helps. Below is only a snippet of "px auxw", there are still many more processes of the same.

After this, I installed the package again. You can see from the below, that on the Tue around 09:00 the package was installed. It uses a bit more CPU, but nothing scary. Then at around 12:00 it jumps up quite a bit. Then at the end of the graph it's jumped up again, so it looks like it's on it's way out.
