Never mind, I resolved the issue by reading a bit more. Sorry to waste
the thread.

I think the reason is that there is nothing called thread.id and thats
why
threads die as they start excution

Now, this is strange reasoning. If we’re guessing: the reason is more
likely that main thread exited without waiting for other threads.
See:

17:00:15 OPSC_Gold_bas_dev_R1.2.3$ ruby -e ‘Thread.new { 10.times { p
1; sleep 10 } }; puts “done”’
1
done

Kind regards

I think your code still isn’t quite what you want. Try

require ‘thread’

threads = []
mutex = Mutex.new
STDOUT.sync = true

list = %w(aS, bS, cS, dS, eS, fS, gS, hS)

for space in list
threads << Thread.new(space) {|numericalSpace|
while true
mutex.synchronize do
puts “#{Thread.current.object_id}: #{numericalSpace}”
end
sleep 2.5
end
}
end

threads.each {|eachThread| eachThread.join}

Hi guys,

threads = []

list = %w(aS, bS, cS, dS, eS, fS, gS, hS)

for space in list
threads << Thread.new(space) {|numericalSpace|
while 1
puts “#{Thread.id}: #{numericalSpace}”
sleep 2.5
end
}
end
