VMware EXSi4.1.0 duplicat vm entries

UPDATE: Observium still adding duplicate VMs after it deleted all duplicates a few days ago.

I have no idea. I just said "Temporary workaround which may work". Strangely, all the duplicate VMs added as duplicates were deleted a couple of days back. I'm running CE and did not do any code updates. I just let the cron job run and did not stop it to test what I thought might solve the issue temporarily as our network guys were adding new devices daily. My VM count increased a lot but suddenly all duplicates were removed in one random cron job run. Only the actual number of VMs remain. I dont know for sure what is causing this issue. I suspect VMware giving faulty data/unique ID for each VM every time Observium polls for changes. I suspect Observium deleted all duplicates one day as it did not see those IDs for a few days. I could be wrong. If anyone familiar with Observium's workings could shed some light on this, then it would be great!

But if i run manually in future in that case will it create duplicate VMs?

Temporary workaround which may work is to disable the discovery cron job which runs every 6 hrs and run it manually whenever there is a need to "discover" changes in the network.

This is getting very annoying, Please suggest what should i do? every days VM getting duplicate. I have to fix it ASAP. How should i expedite to someone?
