After upgrade to v4.39, I am getting 100% cpu from time to time, there are few alerts "Zysh daemon is busy"
and widget keep loading.

Any suggestion about it?

  • The CPU is going up quickly if I click refresh widget quickly.


  • Trying to set the widget refresh interval to 300, but somehow it is reset to default 0. What's the correct way to update it

    Hi @michaelJin,

    We need to check why zysh daemon is busy on your device remotely.

    I'll contact you in private message for remote access information.
