Are the stale with this specific error CIs VMware virtual objects, by any chance? When I started digging deeper into those classes with this error, they were almost all related to the vmprobe integration.
The Discovery for vCenter documentation provides this;
When a vCenter CI, such as a virtual machine, is removed, the ServiceNow instance marks it as "stale" in the CMDB, using either of these procedures:
- When Discovery runs, it creates an audit record in the CMDB Health Result [cmdb_health_result] table for the missing CI and marks the CI "stale".
- If the instance is configured to collect vCenter events, the system can also create a "stale" audit record for the CI in the CMDB Health Result [cmdb_health_result] table from the VmRemovedEvent event, without having to run Discovery.
and recommends a CMDB Remediation Rule to auto-delete those stale CIs.
