Kathey Marsden commented on DERBY-4319:
---------------------------------------
There was some network maintenance that seems to be what got the aix machine
out of its problematic state. Myrna said in the past after reboot (this time
it wasn't reboot but reboot of the router) it will work for a while and then
start to consistently fail. I kicked of fifty runs of the derbynet suite to
see if I can get the machine back into the problematic state.

> The test run for 10.5.2.0 hung in suites.All. The console output (the run was
> with -Dderby.tests.trace=true) showed ttestDefaultProperties had successfully
> completed but the run was halted.
> ps -eaf | grep java showed the process that kicked off suites.All, and a
> networkserver process with the following flags:
> - classpath <classpath including derby.jar, derbytools.jar, derbyclient.jar,
> derbynet.jar, derbyTesting.jar, derbyrun.jar, derbyTesting.jar and junit.jar>
> -Dderby.drda.logConnections= -Dderby.drda.traceAll=

> org.apache.derby.drda.NetworkServerControl start -h localhost -p 1527
> This process had been sitting for 2 days.
> After killing the NetworkServerControl process, the test continued
> successfully (except for DERBY-4186, fixed in trunk), but the following was
> put out to the console:
