Mmmm, seems to be a script with almost the same as the options as I
previously used. Must be some difference in the options though
(-hidden?). Here's the output of etop after a few minutes. As you can
see the process zu_server has 16233 messages in it queue and the memory
usage has blown out. What is the function gen:wait_resp_mon/3? Would I
be right in guessing it's the other half of gen:call? If so how do I
tell which call it's waiting on?
