Environment

• VMware Cloud Director 10.6.1.2

Cause

The issue occurs when the system cannot fetch the Avi system limits. In the fallback path, a misconfigured logger attempts to format data incorrectly, resulting in a java.lang.NumberFormatException.

Resolution

This issue is known issue and has been fixed in VMware Cloud Director version 10.6.1.3.
