Is there a serious of steps, log files, etc. that would be helpful to
provide to diagnose issues?
(Sorry, I'm sure I have asked the diagnose question before).
I am having an issue with a specific client system.
SEDNA seems to have died. SEDNA is not responding to any request.
(If I rebuild the system from scratch using the same data and procedures,
the system dies in about the same spot in processing)
The last line of the SEDNA event.log
LOG 08/01/2012 17:59:10 (TRN xrdb pid=2693 sid=47 trid=-1)
