Excuse the late reply.   Maybe you or someone can try this next time:

If you can't restart the node then check for a stuck rgmanager 
process.   It can get to an un-killable state.


so do
ps afx


222025 ?        Ss     0:00 /bin/sh /etc/init.d/rc 6
  222028 ?        S      0:00  \_ startpar -p 4 -t 20 -T 3 -M stop -P 2 -R 6
  222044 ?        S      0:00      \_ /bin/bash /etc/init.d/rgmanager stop
  225986 ?        S      0:00          \_ sleep 1

  rgmanager  is in an un killable state.

  kill -9 on the  running rgmanager process did not work.

  so kill the /etc/init.d/rgmanager stop process .
in the above you'd
kill -9 222044


here that allowed the machine to procede with a reboot.
