Hi < Tsang Yong> that s a Dask log which you ll usually see if your task has seized the CPU entirely so no background processes can run are you doing something particularly intensive

Jeremiah · Answer

Another way you can see this is if you re running a dask worker scheduler on something like a laptop and you sleep the computer when you turn it back on it ll show this message

Tsang Yong · Answer

yes it s a CPU intensive task

Jeremiah · Answer

Ok that could be normal just Dask warning you that it wasn t able to run any background task while your task was running
