Hi there,

while looking at the Console's log entries ("Application - Console") it
seems that launchd tries restarting the rxapi daemon in 10 second
intervals. Is this intentional or a potential problem?

This is how the rxapi-daemon gets started (copied from Bruce's script):

    launchctl load -w /Library/LaunchDaemons/org.rexxla.oorexx.rxapid.plist
      

with the content:

    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" 
"http://www.apple.com/DTDs/PropertyList-1.0.dtd";>
    <plist version="1.0">
    <dict>
        <key>Disabled</key>
        <false/>
        <key>KeepAlive</key>
        <true/>
        <key>Label</key>
        <string>org.rexxla.oorexx.rxapid</string>
        <key>ProgramArguments</key>
        <array>
                <string>/usr/bin/rxapi</string>
        </array>
        <key>RunAtLoad</key>
        <true/>
    </dict>
    </plist>
      


Here's a sample of log-entries (after a fresh reboot to test whether the
launchd is indeed processing the rxapi daemon)::

There is at least another daemon that gets restarted, other daemons do
not get restarted, which is the reason for querying whether the observed
behaviour is o.k. or not.
