[Observium] losing device information after adding IP SLA

Hi,

We have a few devices in our Observium installation which lost some sensor en memory pools during discovery. See below. It looks like the problem started around 5 days ago.

[cid:image004.png@01D16E44.AA924840] It looks like that after enabling a new IP SLA config on a new device, and running a discovery, first the new IP SLA entity appeared. But after waiting a few minutes, the IP SLA and more entities, disappeared. [cid:image005.png@01D16E46.CFB02A50]

I attached the discovery debug information for both hosts. How can we get this back to work? Did anything change in the discovery and/or IP SLA around 5 days ago? Thanks and regards, Bastiaan
