Uwe Kubosch updated DERBY-4027:
-------------------------------

    Attachment: derby.log

Here is a derby.log with debug information.  I hope you can make sense out of 
it.

An additional information:  We recently (less than 2 weeks ago), started 
persisting ActiveMQ messages using derby.  ActiveMQ is running embedded in the 
same JVM, so we access 2 derby databases in the same JVM.

> I don't know too much about JRuby, but I assume you are not using JDBC 
> directly?

We access JDBC using ActiveRecord, but I expect this should not make a 
difference.

> Also, is the data you are inserting ASCII only, or are you inserting for 
> instance CJK or nordic characters?

Nordic characters are definitely possible.

> Finally, in the description you wrote "It started yesterday". Does this mean 
> that the application has been running successfully for a longer period of 
> time?

Yes, the application has been running for long durations earlier, but we 
constantly develop the application, so circumstances change, and we regularly 
recreate the development database.

Two production databases are still running without problems, so something we 
changed in the last few days is triggering the error, but we are unable to 
identify any special changes.  We are possibly exercising the database slightly 
more than earlier by deleting/inserting some rows that were updated earlier.

> And on the different systems, are you running against the same database or 
> regenerating it from scratch?

All systems own their own embedded derby database.  There is no database 
network access.
