Subject derby.log not truncating on reboot
Date Mon, 10 May 2010 20:40:57 GMT
I have a service that shuts down the Derby database after it is done using
it.  This is because on Linux I was getting errors "too many open files"
unless I did this - I use a lot of databases, and when all of them are
booted it starts using up too many resources.

But now my problem is that every time I shut down a DB, and every time I
boot a DB, it adds a message to the derby.log file, and over time the log
file grows and grows.  Is there any way to silence these messages?

Here is an example:
