large derby log
Derby.log keeps growing and the PC eventually runs out of disk space. It's up
to 4 GB. Derby version is 10.5.3.0.
Below is a tail of derby.log:

Can someone tell me what's causing this? Is my DB corrupt?
Thank you!

Thanks Knut Anders, from your clues we were able to determine that the
programs aiming at the Derby network server port were some old applications
expecting to connect to a Cloudscape DB. Not surprisingly, that doesn't
work.

The above exception means that the server doesn't understand the initial
handshake from the client. If you've ruled out the suggestion in the
error message (that either the client or the server has SSL enabled
whereas the other party doesn't have), could it be that some other
(non-Derby) application attempts to connect to the port on which the
Derby network server is listening?
For example, I see the exact same exception being written to derby.log
if I start a network server listening to the default port (1527) and
then attempt to open this URL in Firefox: http://localhost:1527/.
