Hi all :slight_smile: How can sleep(0.001) error? ┌ Error: │ EOFError: read end of file │ Stacktrace: │ [1] wait │ @ .\asyncevent.jl:159 [inlined] │ [2] sleep │ @ .\asyncevent.jl:265 [inlined] This happend on Windows. Julia v10.0.0 Thanks all!

Hard to give a minimal working snippet. Just can tell that it happens almost never (my feeling 1 in 10^15). The surrounding code is a while-true with a inner try-catch and a pulling ccall. All this runs in a separate task.

[image] SunnyUser: Hard to give a minimal working snippet. It shouldn’t be hard to share the code you’re actually trying to run. You only showed a partial error message.

I can do that… But I have to remove company code. But the following function gets spawned in at task. function get_next_item() while _IS_RUNNING[] try return_buffer = managed_allocating_ccall( ccall_get_next_item ) if isnothing(retur…

I got this error again in production. I have no idea to debug or fix it. Can me help anybody?

Wrap sleep in a try-catch block and ignore EOFError: try sleep(0.001) catch ex ex isa EOFError || rethrow() end

Thank you for that idea. But why isn’t that in Base or why does it happen at all? I mean I don’t want to wrap the sleep method all the time

This should get a better error message. The error is thrown here: JuliaLang/julia/blob/222231f047462bcb2cef3e402c86cf41df82414d/base/asyncevent.jl#L159 unpreserve_handle(t) end end iolock_end(…

It seems like for sleep the code should be modified so no error is thrown in that case. It doesn’t seem helpful to error if it “overslept”, in fact that seems expected in some cases.
