Subject [jira] [Created] (CLOUDSTACK-9283) cloudstack-usage fails to start throwing Integer exception during PID retrieval
Date Wed, 10 Feb 2016 13:28:18 GMT
Linas Žilinskas created CLOUDSTACK-9283:

             Summary: cloudstack-usage fails to start throwing Integer exception during PID
                 Key: CLOUDSTACK-9283
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
          Components: Usage
    Affects Versions: 4.7.0
         Environment: CentOS 7, systemd, packages from official repo
            Reporter: Linas Žilinskas

I have very little knowledge of java, but I looked at the code where the exception is thrown.
The code is 
{code}_pid = Integer.parseInt(System.getProperty("pid"));{code} 

Based on the information I found, I guess the command line requires -Dpid=$$ to be passed,
which isn't. I modified the systemd service to include the parameter and service now starts.
I'm not sure if this is something specific to my environment or not, but seems strange that
this could go unnoticed.
