It's using the WiredTiger storage engine which has good crash recovery support. How does the crash present?

  If I can get the unifi device and version I will follow up with unifi directly.
  - ComputerGuru 5y ago
    It's device agnostic; this is from the controller software that manages all the Unifi devices on your network. This was the latest version of the controller, available on their website as "UniFi Network Application 6.5.55 for Debian/Ubuntu Linux and UniFi Cloud Key" (Cloud Key is the appliance they ship that simply runs Debian w/ the package installed). My email is mqudsi at neosmart dot net; I'd love if you could let me know what happens.
