After loading several million records via odbc, the server is suddenly unresponsive but can be restarted.  When using jdbc, the server crashes, again after several million records, but cannot be restarted.  Performance and usability are impressive with a million records or so but I cannot seem to load more than that without consistent problems.

Is there any way to make the server - and ideally the database - usable again?

Thank you in advance,
