SGE fails in rmprocs

[aquaresima]

Hi,

after adding and using 4 processors, ClusterManagers fails when it s time to remove the procs. Below a MWE

using ClusterManagers
using Distributed

N_JOBS = 4
addprocs_sge(N_JOBS; queue="single.q")

@everywhere using Dates
@everywhere  function test(id, info)
	sleep(10)
	# println(second(now()))
	return id, second(now()), info
end

futures = []
#works
for i  in workers()
	global futures
	## fetch them inline
	println("start: ",fetch( @spawnat i getpid() ), " ", second(now()) )
	## fetch them later
	result = @spawnat i test(getpid(), "pull results" )
	push!(futures, result)
end

# works
for i  in futures
	data = fetch(i)
	println("end: ", data...)
end

rmprocs(workers())

The error is the following:

ERROR: LoadError: MethodError: no method matching get(::Base.Process)

Thanks for your help

PS.

It gives a similar error if I end the program without running rmprpocs:
