This is great, if you&#x27;re planning to do many things with erlang, our you have a lot of time. If your friend has a weird problem and comes to you because you have a reputation for figuring things out that you&#x27;ve earned by using strace, then you use strace. Incidentally, I&#x27;m reading this because I use erlang, but it took about a minute to see the problem (tcp port exhaustion) from the strace.
