Dear,

After upgrading our Jenkins instance from Jenkins 1.509.4 to Jenkins 1.580.3 (identified as LTS).

Following this upgrade, we are facing stability issues and need to restart our Jenkins instance once or twice per day (which has an important impact for the company)

The heapdump enclosed to this ticket show that several threads remain blocked in the JVM.

"Finalizer" daemon prio=8 tid=3 BLOCKED

As a result, CPU usage is increasing and the JVM fails in an OutOfMemory.

As short term action, we have already increased by 4Gb the RAM of the server, but of course, it does not solve the issue, it only reduces a bit the impact.

Have you already identified this issue ?
If yes, is there a fix ? In which release ?

Best regards
