[Hans Nordebäck]

I suggest to change amfnd and amfwd to call daemon_exit instead of exit.

[tickets] [opensaf:tickets] #2321 Incorrect error messages "mkfifo already exists" observed in syslog

[Hans Nordebäck]

ok, I see, this is because amfnd and amfwd calls daemonize but don't call 
daemon_exit but exit(). Their respective fifo file are therefor not deleted.

This mesages only observed when we start opensaf after perfoming "opensaf stop" 
operation. 

Sequence : Stop opensaf> Start opensaf (ERR Message will observed in syslog)

while there is no impact of these syslog ERR on opensaf services, opensaf 
successfully started  without any issues.

[Hans Nordebäck]

perhaps this message can be changed to a trace message? The fifo file is 
deleted at graceful shutdown but if e.g. the node has crashed the fifo file is 
not removed and at the next node start this log message will be written.
