> Key: CLOUDSTACK-6328
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-6328
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: SystemVM
> Affects Versions: 4.3.0
> Reporter: Saurav Lahiri

> From the mail on dev list
> ===========================================================
> 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.
> ====================================================
