  • Hi,

    I have a demo site, that was running the free version on an ODROID XU4, but we had an "out of memory error" and subsequent shutdown of mango a couple of times.

    We have decided to upgrade the hardware to a Windows 7 box, i5, 8Mb.
    I downloaded the latest free version from the website (link)(;jsessionid=DB6F85B8DD31CEBE2E413F9FD963DB52), and installed, setup java, widows service etc, and them imported the json config file as retrieved from the old ODROID.

    The issue I have now is that it shuts down periodically, due to a "timed license"

    I have not had this before.

    Please help, as I am trying to get these guys to invest in the commercial license.

  • Hi Hayden,

    We prefer to handle license issues over emails to

    Please provide the GUID and situation, and invoice number if applicable. Generally MangoES licenses are not transferable, but certainly something can be worked out.

  • Hi Phil,

    I will send an email, but it is not an ES license, just a free version.

    The ODROID was not an ES.

    It is almost like the link to the free version was wrong somehow. (


  • Ah, my mistake, I misunderstood! I will check on that, and am happy to grant you a trial license if you would like to use the NoSQL database while developing your solution.

  • Hi Phil,

    Would you please be able to provide a link to the free version, without the NoSQL DB?

  • On emails now...

  • I checked the free bundle, it doesn't seem to have the NoSQL module so I'm not sure what happened there.

    See ya in the emails!
