@Claus: I do not have yet a patch for it but it would be great if you could provide one!

> Configure Jackrabbit to use a DbDatastore and a MySQL database to store the content.
Now, if do not configure the max_packet_size in MySQL you can only store Blobs that are smaller
than 1MB (default). If you now add a Node in Jackrabbit that has a binary property and try
to store a Blob larger than 1MB. Jackrabbit gets now a SQLException for the first time it
tries to store the binary value. But there is failover mechanism implemented that now tries
to persist the bin value for a second time. Now storing the value works because the InputStream
has hit its end and there are no bytes left. That results now in an empty binary value that
is stored and the client doesn`t get informed about that.
> Same problem occurs if you hit the table space limit with an oracle database.
