Can't terminate accounts (old WHM version)

Hello, We have an old CentOS 5 server running the latest WHM version (56) available for it. Yes, I know it's an old version and it should be updated but this is just not possible at the moment. When we try to terminate an account, it doesn't work. The error in the logs starts with: Invalid lock file: ', mpid=23545, TLS, session=' is not a PID. at /usr/local/cpanel/3rdparty/perl/522/lib64/perl5/cpanel_lib/cPanel/StateFile. pm line 63. We tried various workarounds, which have failed. Any ideas? Thanks, Dragos

  Are you using an NFS mount? What is the output of the following? cat /root/servers_queue.json.lock

  There is no NFS mount on the server and the file /root/servers_queue.json.lock doesn't exist.

  Hi @dragos03 Now I'm scratching my head, I went through a bunch of old tickets from v56 and those two were the only results I got, with the exception of 1-2 that were related specifically to corrupt/invalid userdata. What's the exact error output in the cPanel error logs at /usr/local/cpanel/logs/error_log

  Thank you for that. Is there a file in /var/cpanel/taskqueue that looks like this: , mpid=23545, TLS, session=

  No, there is no such file.

  So, the whole reason for the error you're getting is the presence of that file....somewhere. Without access to the server, it'd be hard to tell you where it's located, but you can see it quoted in the error message: Invalid lock file: ', mpid=23545, TLS, session=' is not a PID
  So, either that file exists or it's referenced in /var/cpanel/taskqueue/ in one of the files there as a current PID. What's the output of the following: ls -lah /var/cpanel/taskqueue

  What's inside of servers_queue.json.lock

  Indeed the reference to that invalid lock file was in there, I deleted it and now I can terminate accounts. Thank you very much for your help.

  Awesome, I'm glad that resolved the issue. I do hope you update soon as well. What is holding you back exactly?

  Well, most of our customers don't want to move to another server, as long as the current one works, in order to avoid downtime, the change of IPs, etc. But we will migrate them all to new servers as soon as WHM will be available for CentOS 8.

  Ahh I missed the part where you said you were on CentOS 5! I just saw cPanel/WHM v56 :) It seems at this juncture that moving once CentOS 8 is available is the smartest choice and the one that will provide you with the most longevity. There are a couple of internal teams working on CentOS 8 compatibility right now and hopefully, we should be prepared to support it soon.

  Indeed, that's the plan. I hope WHM will soon be available for CentOS 8.
