As per Symantec: "The Windows Event ID 7039 reports, "A service process other than the one launched by the Service Control Manager connected when starting the VERITAS Private Branch Exchange service. The Service Control Manager launched process 4068 and process 512 connected instead. Note that if this service is configured to start under a debugger, this behavior is expected."
This behavior is expected and can be safely ignored. The message is generated as a result of the way the PBX service was implemented. The PBX binary is not written as a pure Windows service. Instead, when the Service Control Manager starts the service, it launches a batch file that in turn starts the processes". See the link to "Symantec Support Document ID: 286761" for details.
