R sessions not terminated with paralleStop in multicore mode #55

Closed pazthy closed 5 years ago

pazthy commented 6 years ago

We are running parallelMap with som mlr functions in the structure:

parallelStartMulticore(parallel::detectCores())

l_ply(seq(100),function(x){

makeResampleDesc

...

}

)
parallelStop()

We observe that not all the R processes are stopped in some of the iterations, and at the end of the 100 iterations we have a number of R processes that do not terminate.

Can you provide a minimal working example? Did you activate parallelism in plyr?

Hi, in this case we need a reproducible example, preferably using the reprex package.

Since this issue is already more than 1 year old and we had no similar complains, I'll close here.
