-----------------------------------------
Summary: Prevent console proxy support scripts from spawning
multiple java processes
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.
