Environment

VCF Operations for Networks 6.14.1

Cause

The inventory SDM is being dropped due to its large size. This results in the inconsistency checker deleting objects that lack inventory. Consequently, applications are being deleted after each discovery process every day.

Resolution

To fix this issue a configuration change is needed on the VCF Operations for Networks platform appliance to allow change max allowed SDM size which should resolve this issue.
