trick is the ocfs was sending the alert message to the console only (I wonder
why it does not also leva traces into syslog, my best guess is it tries to
shutdown as fast as it can, and sending a message to console is faster than
sending it to syslog - but I'm in no way a linux guru...).</SPAN></FONT></DIV>

<DIV>Gaetano,</DIV>
<DIV> </DIV>
<DIV> If o2cb or CRS is killing the machine, it usually
shows on /var/log/messages with lines explaining what happened. Take a
look on the /var/log/messages just before the last "syslogd x.x.x:
restart".</DIV>
<DIV> </DIV>
