Description
The diskusage.cgi messages started being logged in cPanel version 11.100. Previous versions of cPanel do not generate any messages, which is the expected behavior. Show Current Disk Usage functions properly despite the messages being generated in /usr/local/cpanel/logs/error_log.
We've opened an internal case for our development team to investigate this further. For reference, the case number is CPANEL-39987. Follow this article to receive an email notification when a solution is published in the product.
Workaround
The diskusage.cgi messages can be ignored.
