Locked logs files and cannot delete a job or folder

[l0id...@gmail.com]

Hello,

I am constantly getting this error in Jenkins when I try to delete a job or
folder either manually through UI or by calling API.

The processexplorer was used for realizing what process locks a log file - that is the Jenkins's service.
Service is running under a special user account (not the default one). This account don't have any issues with the filesystem permissions.

Yes, the folder where is Jenkins is installed is "tools)"

What version of jenkins?

There was a bug fixed around this area since time around 2.3x IIRC.

Otherwise may be someone is viewing the console from the run. Windows will not let you delete a file even if it is the same process that has it open and owns the lock.

Can you see this on the latest Jenkins on a new test job (to make sure no one else interacts with the job) also what type of job (pipeline Freestyle etc)

[l0id...@gmail.com]

The current version is 2.46.2
Is it safe to update from this version to the latest (will I be able to rollback) and what should be installed additionally (like java 7,8)?

I am sure that nobody watches logs, I just create a job, run it, try to delete and get the error.
