hplip taking 100% of CPU and running CPU temps up to 80C

RayDude

According to internet searches, this used to be a thing a long time ago.

But for me hplip is crashing and taking 100% of a CPU causing the CPU to run hot.

The kitties like it, but me not so much.

I killed the process, but I was wondering if anyone else has seen this issue and has an idea how to prevent it from happening.

Are you using the portage version or an out of portage version?
Which software release?

All I can say is that I have some remote managed machines with net-print/hplip-3.22.6 installed and don't see this behavior...

If you can reproduce this on demand, you could rebuild with debug symbols, trigger it, then capture a core dump to see where it is looping. This behavior can indicate that the application is expecting some condition to become false as a result of the application's logic, but the condition remains true, causing the application to remain awake and continue trying to change the state.
