HTOP not showing CPU anymore

I noticed that hop lost its cpu bars.

 

I tried to add them but ger error:

munmap_chunk(): invalid pointer

 

Anyone else have this problem?

 

Thanks

This is a classical memory corruption.

 

Htop has possibly crashed. During a crash Htop emits a backtrace with some info.  If you have the backtrace info, please post here with your Htop version.

 

You can also try a few things:

* Remove every meter, F2 and delete all the meters, exit. Start again and add one cpu bar. If it is Ok then proceed with the rest.

* If you have some skills build Htop with debug info, the backtrace will show the function previous to the free() memory.

Ok, thanks.

 

So it seems like the bars and meters work. The problem is saving the settings.

 

I am doing it both as user and with sudo. F10 "Done" results in invalid pointer.

 

Thanks

Try  removing the config file with Htop closed:

 

sudo rm /root/.config/htop/htoprc

 

Start Htop and make your changes.

Thanks, removning it does not help.

 

However, creating a new one works. But htop seems not to save any changes. But no crash.

 

Could you post the armbian default or whatever you have?

 

Thanks

And the nice thing, you can have Htop in a Browser...

That is neat! Shell in a box, have to look into that.

 

For anyone with the same problem I had, here is a htoprc to start with:
