    Description

      Customer reports a persistent apparent leak of about 50-100 threads per day. The thread count seems to jump each day after midnight. These jumps are consistent with Provisiond's daily rescans triggering the leak.

      Attaching resource graph of JMX data showing long-term thread count trend, plus thread dumps from consecutive days from a running 20.0.2 install.

      Much more background and history dating back to the original 18.0.4 upgrade is available from the support ticket history (see Environment).
