Hi,

I've got the API set up to export functionality from a package, and it works without any problems. However, if I leave the API running on an EC2 instance via a screen, I get a segmentation fault after awhile. Any idea why this may be?

    I don't know much about the EC2. do you have some output messages?

    could you test it with master branch?

    The following is the result of adding Bukdu.jl via the repo link, and the version is listed as v0.4.12 #master when I did run status in the Pkg Manager

    I should note the fault now occurs after the first request is made, but previously is occurred after an undetermined number (more than 10-20 at least)

    @wookay I think since the version is still the same it isn't grabbing the newest changes?

    to do not getpeername for a while,
    I added enable_remote_ip option to Bukdu.start (default is false)
    I hope it just works.

    I've had the API running for a few days now and haven't encountered this error yet. This is the longest it has run without problem. I didn't enable_remote_ip with Bukdu.start(), but seems to be working.

    Thank you!
