I’m using Jenkins 2.426.3.

I’m using a freestyle project and build retention policy is configured as follows:

• Strategy: log rotation (only possible choice)
• Days to keep builds: 10
• Max # of builds to keep: 10
• Days to keep artifacts: 10
• Max # of builds to keep with artifacts: 10

I noticed the builds are kept less than a few hours.
I often go back to check the job only to find build history is empty.
