      The value of pc was almost the same in all of the crashes.



      A DESCRIPTION OF THE PROBLEM :
      After upgrading to JDK13 and enabling ZGC, we saw these crashes on a number of instances. All of them happened at approximately the same time after ~20 hours of uptime. We didn't have a chance to grab logs but will try to grab them once it happens again.
