Derby hangs on large batch insert

[Robert Enyedi]

In a Derby database we are trying to insert a large number (1300) of 
records in a batch. We are using the Derby network client.

We do the batch insert under isolated conditions in a unit test . When 
executing the test, both the unit test and the Derby server process 
freeze at the point of the insert (during 10 minutes there's no disk 
activity nor processor load for the processes).

Is this a bug or just a server configuration issue?
