  • It's been running well - until I changed the fields to be collected in an Excel spreadsheet. I think the problem was caused by Mango not being able to find the data variables entered into the spreadsheet.

    The problem is it won't restart. The following error message is generated - but it doesn't help me fix the issue. Suggestions?

  • After waiting 12 hours and rebooting the processor, for no obvious reason Mango restarted. Any suggestions?

    Rebooting the processor? What does that mean?

    Your full log may shed some light.
