One important update: ( I damn sure, now someone from you can help me out )

*Updated: This is the additional output which I see after the previous line*

*[[  OK  ] Started Xyz agent.\n' *

*If you carefully see, there are 2 opening square brackets( '[' ), from
this it looks like that systemd is overwriting the log messages. The first
"[" comes from the initscript's "[ OK ]". Can somebody explain this better
? *
