             Summary: Karaf doesn't start after not clean reboot, because stored PID corresponds to running process
                 Key: KARAF-5206
                 URL: https://issues.apache.org/jira/browse/KARAF-5206
             Project: Karaf
          Issue Type: Bug
    Affects Versions: 4.1.1
            Reporter: Andrea Tarocchi


If Karaf is shut down in a disorderly way – a VM is terminated for example, or there is a power failure, then on occasion it will fail to restart when the host starts. The problem is that the stored PID in instance.properties might correspond to that of a process that is already running but is not the karaf one.

step to reproduce it:
- Find a PID from an already running process (which is not the karaf one) and place it in *instances/instance.properties* file as value of *item.0.pid* key
- Try to start karaf with *bin/karaf* (or bin karaf.bat)
