 Contact Cisco TAC to remove any identified misconfigured objects before performing the upgrade to prevent policyelem crashes.
 The [CSCwd40071][68] defect affects versions 5.2(5c) and later with a fix available in 6.0(1g). However, the issue will only be triggered during Apic upgrades crossing 6.0(4c) due to [CSCwh80837][67].
 
+
+### Svccore Excessive Data Check
+
+Due to excessive `svccoreCtrlr` or `svccoreNode` managed objects, Apic gui stuck in loading multiple queries.
+
+The svccoreCtrlr and svccoreNode objects represent core files related to Apic and Leaf/Spines process respectively.
+
+Due to [CSCws84232][67], the APIC GUI may become unresponsive after login, with dashboards stuck in a continuous “Loading…”state.
+Administrators may be unable to access or operate the APIC GUI, potentially impacting day-to-day management or upgrade.
+
+This check will verify the count of the `svccoreCtrlr` Managed Object and raise and alarm with the bug if object count found more than 240. Remove the content or objects of `svccoreCtrlr` or `svccoreNode`. Contact Cisco TAC or upgrade to a release containing the fix for CSCws84232 before proceeding with an upgrade.
