Great point. I even found some ID 4226 from around that time a few days ago. However, I cleared my event log, repeated the test and the issue, and no entries appeared in the event log. So although this sounds promising, it doesn't appear to be 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 gives an exception when connecting. The Thread.sleep statement has been made as high as 5000 ms, and exceptions still sporadically occur.

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