Re: InstantDB: database shutting itself down without error


You should never have multiple threads accessing the same connection 
unless you're using some pooling mechanism that insures that two threads 
can't using a connection at the same time. This is true for any JDBC 
connection, not just InstantDB.

I don't know if this can cause your problem or not, but it seems likely.
