cPanel httpd.conf ^M

We came across this weird behavior where a VirtualHost container of a few random domains inside httpd.conf were including a ^M carriage return.

ServerName domain.tld
ServerAlias www.domain.tld
ServerAdmin webmaster@domain.tld
DocumentRoot /home/user/public_html/user^M

The Apache daemon went down frequently because of this as any user which made any modifications to their Apache configuration (addon, parked and subdomains), the daemon was restarted and all web services came to a halt due to the carriage return in the httpd.conf.

cPanel technicians reported they have seen this issue but have not been able to replicate it. Fortunately, the issue hasn’t occurred again and we hope that cPanel can identify and fix this bug.
