According to this post: http://lists.mysql.com/mysql/212112, try decreasing the max-connections in my.ini to 400 (or even 360 - that it the most connections you will make based on the *-ds.xml file setting).
Also, monitor the thread count on the mysqld.exe process - this will give a rough idea of how many connections you have. Or you can use the MySQL Administrator to monitor the number of connections. I'm sure there is also a query you can run in the mysql command-line client to get this info, but I don't know the syntax offhand.
Another thing to consider is the memory usage on the database node. Are you, by any chance, booting that system with the /3GB boot option?
