[OmniOS-discuss] Postfix service: syslog reports "fatal: the Postfix mail system is already running" every second

[Andries Annema]

In the mean time I tried upgrading the separate test-system from r151022 
"vanilla" to the CE-edition -  r151022i by now - hoping this might 
somehow also solve the below postfix "already running" error. But, it 
didn't.

Again I tried the solution that worked on r151014 and also a reboot, but 
without success.

This "Postfix mail system is already running"-issue is all over the 
internet - not specifically on Solarish-systems, that is - but I am 
clearly missing something here, as I don't seem to get the issue out of 
there.

Is there anyone out there with some ideas on this, pretty please?

Thanks.

Andries
