Environment

VMware Cloud Director

Cause

The issue is caused by incorrectly formatted values in the '/opt/vmware/vcloud-director/etc/log4j.properties' file.

Resolution

To resolve this issue, please follow these steps:
 

1. Before making any changes, create a copy of /opt/vmware/vcloud-director/etc/log4j.properties for safekeeping.
2. Open the log4j.properties file and look for any configuration properties with a value that matches the one reported in the error message (e.g., 2:0480KB).
3. Change the incorrect value (e.g., 2:0480KB) to the proper format. In this case, the correct format is 20480KB (removing the colon).
4. Once the value is corrected, restart the VCD service with the following command: service vmware-vcd restart
