Henri Yandell commented on DBCP-205:
------------------------------------
Agreed - seems to be that the JDBC driver/db just doesn't like the amount of
activity.
Not that I grok how the driver could be running out of client side ports to
connect from; there're tons of those aren't there?
Might be a SQL Server driver specific bit I guess if it's trying to define the
actual port to connect from and it's getting screwed up for some reason.
