We are migrating to SDL WEB 8.5, publication works fine, but I've realized the incoming queue folder has a lot of files with .lock extension. So I've reviewed the log and I found this error:

ERROR FSDeployerQueue - Queue [Id=ContentQueue]. Failed to delete serialized command 'D:\SDL\live\service_folder\queue\incoming\ContentQueue\tcm_0-2479122-66560.Content.json'

if I go to that folder, I find this file tcm_0-2479122-66560.Content.lock

I've cleaned the folder and sent to publish again, and I was able to confirm, all files are renamed to .lock and remains into the folder instead of being deleted.

Any idea why this is happening? thank you !!

  • The most likely reason is that the service is running as a user who does not have permission to delete files in that folder. Have you checked the file system permissions? Sep 28, 2017 at 10:33
  • For others stumbling across this - I've also seen something similar when an anti-virus checker was scanning the incoming folder making some deletions impossible; this was more difficult to track as it seemed random given it wasn't all files (or the same published items each time) Oct 13, 2017 at 9:35

I've re-installed deployer service, after that, files are deleted from the folder. I don't have the explanation of what was wrong, but at least, I have the solution to this problem.

thanks Carolina
