The problem of terminating an async task has been discussed over here:

> Hello, I search a bit here and on the web and found out that obviously there is no “official” way to terminate a started task in julia yet. However, throw an Interruption error seems to work as a workaround for now. But now I would like to do it from within a function. Here is the example. The stating case is working but the stopping case is not. function switch\_timer(switch) if switch global t = @async while true sleep(1) end else @eval :(Base.throwto(t, InterruptException())) en…

The conclusion seems to have been

```julia
task = @async some_long_running_function()
sleep(5) # give it some time to run
schedule(task, InterruptException(), error=true) # send an interrupt exception

```
