Stuck in Change Hostname

Hi all, in a new server (installed CPanel yesterday) I tried about 8 hours ago to "Change Hostname". It seemed to finish ok, then it asked for "Add an A Entry for Your Hostname", which I did as prompted, also ok. However, when I click on the "Change Hostname" a warning appears: "Your previous attempt to change the hostname is still running. Please wait until it completes". When using "/usr/local/cpanel/bin/set_hostname abc.def.com" I get "Changing hostname to abc.def.com...Failed! Cannot set the hostname; there is already hostname change in progress. The /scripts/check_valid_server_hostname diplays ok. Any ideas?

  Forgot to say that ~4 hours after the "Change Hostname" I tried to fix it by restarting the server. Still, I have the exact same situation. And it might be needed to change the name again in the near future.

  Is the domain name you're using valid and pointing to the server from your Registrar properly?

  Yes, DNS is perfectly valid. In fact the server responds to both the old and new host names. However, the certificate given out during IMAP/POP3/SMTP/FTP connections reflects the old host name.

  What is the Kernel Version ? Is it outdated ?

  Hi again, it's CentOS 7.2 kernel-3.10.0-327.22.2.el7.x86_64, WHM 58.0 (build 28), System and Server software is up to date (the System was only installed yesterday and "System Update" only updated 5 packages).

  Hi, for the record, I opened a CPanel Ticket and Jon proposed to just delete the touch file: /var/cpanel/.application-locks/UpdateHostname. In fact hundreds of 1-byte files (the above mentioned plus one for each domain name on this IP) are left there. Indeed, after I delete them I am able to change Host Name, but now every time I try to change the name, the same thing happens, the files remain there and block further attempts (until I delete them again). Obviously, I 'm a little afraid that the process did not finish ok. The logs however don't report any error, as far as I can tell, and everything seems to work.

  Hello, Could you reopen the ticket, or open a new one, so we can determine why the lock files are left in-place after updating the hostname? You can post the ticket number here so we can update this thread with the outcome. There's an internal case, CPANEL-6156, regarding this issue, but additional information about why the lock files remain on the system will help us to address the issue. Thank you.

  I was having this issue, and by adding my IPv6 address bound to my server in the Basic WebHost Manager Setup I was able to resolve this issue for myself.
