Description

I intermitently get network startup related errors in running the nightly full test suite on my laptop, running XP, with a firewall and a VPN - I am not sure what if any of those environmental factors is causing it. I have been mostly ignoring the errors as it seemed like it usually was only one test. I my latest run it was more like 7 or 8. I'll append exact tests as a comment on this issue.

To debug the problem I picked one - org.apache.derbyTesting.functionTests.tests.derbynet.NSSecurityMechanismTest
and ran it in a loop. When I did this it failed everytime after the first one (and the first one intermittently failed). When I bumped the WAIT_TIME up to 300000 and the SLEEP_TIME to 500 in
java/testing/org/apache/derbyTesting/junit/NetworkServerTestSetup.java then the test passed everytime . In 30 runs the
entire test took varying times from 2 minutes to 6 minutes, mostly in the 4 minute range.
