> ===========================================================
> Hi,
> The console proxy supporting scripts run.sh restarts the java process if it determines that for some reason the _run.sh has exited. If the original java process has exited then that is not an issue. If for some reason the java process is still running, then the while loop which calls _run.sh will cause a second instance of a jvm to start, which refers to the same log file namely cloud.out. It appears that two different jvms referring to the same log file
> is causing issues. A way to fix this could be to change the code in run.sh to use the get_pids routine to check and preempt start of a new java process if an existing process is running.
> Please let me know if I have read the situation correctly and if a defect needs to be logged
> for this.
