I was in the gui of my server, and it was unresponsive and told me that CCED was not running. OK. Onto the command line to troubleshoot.</div><div><br></div><div><div style="margin: 0px; font-size: 11px; font-family: Menlo;">[root@hostname /]# ps -ef | grep cced</div><div style="margin: 0px; font-size: 11px; font-family: Menlo;">root 22324 22496 0 21:03 ? 00:00:00 /usr/sausalito/sbin/cced</div><div style="margin: 0px; font-size: 11px; font-family: Menlo;">root 22380 22379 0 21:03 ? 00:00:00 /bin/sh /etc/init.d/cced.init restart</div><div style="margin: 0px; font-size: 11px; font-family: Menlo;">root 22383 22380 0 21:03 ? 00:00:00 /bin/sh /etc/init.d/cced.init stop</div><div style="margin: 0px; font-size: 11px; font-family: Menlo;">root 22496 1 0 06:01 ? 00:00:00 /usr/sausalito/sbin/cced</div><div style="margin: 0px; font-size: 11px; font-family: Menlo;">root 31922 13312 0 21:05 pts/0 00:00:00 grep cced</div></div><div><br></div><div><br></div><div>Hmm.

So that tells me at the same time that I was in the gui, there was a yum update happening, and also at the same time something wanted to restart cced. </div><div style="margin: 0px; font-size: 11px; font-family: Menlo;"><br></div><div style="margin: 0px; font-size: 11px; font-family: Menlo;">In this case, I waited a bit, and it self repaired... once the yum commands had completed. I just wanted to share this with everyone here in case it is useful to anyone in future.</div><div style="margin: 0px; font-size: 11px; font-family: Menlo;"><br></div><div style="margin: 0px; font-size: 11px; font-family: Menlo;">Greg.</div></body></html>
