Symptoms

A managed opmn process can not be stopped / restarted by opmn. The opmnctl status command show the process in "Stop" status but can not be stopped/restarted:


$opmnctl status
Processes in Instance: myinstance.myhost.mydomain
-------------------+----------------------+-------+---------
ias-component      | process-type         | pid   | status
-------------------+----------------------+-------+---------
OC4J               | OC4J_BI_Forms        | 7510  | Alive
OC4J               | home                 | 2028  | Stop


$opmnctl stopproc process-type=home
.
.
.
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
--------------------------------------------------------------------------------
ias-component/process-type/process-set:
OC4J/home/default_island
Error
--> Process (pid=2028)
time out while waiting for a managed process to stop


When checking with ps -ef | grep <pid> the process, it corresponds to a process not managed by opmn, and eventually not owned even by the same UNIX owner of the Application Server / Fusion Middleware installation.
