Great point. I even found some ID 4226 from around that time a few days ago. However, I cleared my event log, repeated
thetest and the issue, and no entries appeared in the event log. So although this sounds promising, it doesn't appear
tobe the case.

I note from your original email that your test platform is Windows XP.
Please check the system event logs for ID 4226.
If you see this message then you have a TCP connection limit issue causing problems.

May be, you have a firewall software that is working and can't keep up with all this connections opened over loopback?

As you see below, something seems....whacked. A simple loop with an unpooled connection (code provided below) often
givesan exception when connecting. The Thread.sleep statement has been made as high as 5000 ms, and exceptions still
sporadicallyoccur. 

I don't know if this is a JDBC driver issue or core server issue. Or something here. But the code is so simple....
