Symptoms

The BPM JVM creates many Timer-NNNN Threads like the following

"Timer-2326" #5544 prio=9 os_prio=0 tid=0x00007fd5f8128000 rc="DOMAIN" ac=2 nid=0xa9c in Object.wait() [0x00007fd55f0d0000]
  java.lang.Thread.State: WAITING (on object monitor)
at java.lang.Object.wait(Native Method)
at java.lang.Object.wait(Object.java:502)
at java.util.TimerThread.mainLoop(Timer.java:526)

The threads look like a regular idle thread, but you the thread number  (i.e. Timer-2326) constantly increases
