problem may involve --maxbranch. I don’t recall needing to set this
before to start 6 mpd procs, one local and 5 on 5 remote hosts, but now to
start more than 4 remote mpd’s, which it says is the maxbranch default, I
need to set –maxbranch=5 for example.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif"'>This
is probably something simple, but when I run mpdboot with a file containing
node names, mpd is started on the all the nodes but the last one in the list
(in the mpd.hosts file) and mpdboot hangs without returning. If I hit ctrl-C it
breaks saying it was in a function “handle shells that echo”, with
the mpd’s that were started still up.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif"'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif"'>I
ran mpdboot successfully before as I recall, with no hanging, and all the
mpd’s requested being started on all the nodes in the file, so it seems
like something simple has changed to cause this issue.<o:p></o:p></span></p>
