[LON-CAPA-admin] Server hung

[Jim Maxka]

Hon-Kie -- My system hung two weeks ago.  I've pored through all the log 
files that Gerd and Nathan have mentioned and I can only see that logs 
stopped around 12:15 including cron log and nothing seemed to work until 
I powered the server back on at 13:15. 

I would be interested if you found some diagnostic.  Thanks --jim
