Maybe it's due to an infinite loop, something like
condition=true
while condition
# if you don't change condition's value in here, you'll never
# get out of that loop
end
It's a good idea to print out variable's values a lot to see what
a program does,
so in the example above,
condition=true
while condition
p 'I am in the while loop'
end
will produce a lot of output, but no error message.
