Hi, Couple of things I found when looking at the dbmgui of the crashed system. This system keeps crashing and auto-restarting. Firstly the backup screen on the dbmgui has a number of HISTLOST entries whose timestamps correspond with that of the crashes.What does HISTLOST mean. Secondly I see a BAD index. What is the cause of a bad index and how do I fix it?? Regards, Ajit
