procid not being set for tcp RFC_5425 syslog message

[KevUKHD]

Hello,

I've encountered a problem that the procid is not being set correctly -> procid seems to be either empty or "-" where long is expected.

        messageSender = TcpSyslogMessageSender()
        messageSender.syslogServerHostname = host
        messageSender.defaultMessageHostname = host
        messageSender.syslogServerPort = port
        messageSender.defaultAppName = appName
        messageSender.defaultFacility = Facility.LOCAL0
        messageSender.messageFormat = MessageFormat.RFC_5425
        messageSender.isSsl = true
        messageSender.sslContext = sslContext
       messageSender.defaultSeverity = Severity.INFORMATIONAL
        messageSender.sendMessage(message)
        messageSender.close()

Code used as above, everything else seems to be working correctly.

I'd be grateful for any help in this matter.

Is there any assistance or insights anyone can provide on this issue?
Am I overlooking a functionality to set the procid (process id) or is this something that can be fixed?
