[jira] Updated: (DERBY-2616) intermittent network startup related
errors in running junit nightly test suite
Posted by "Mike Matrigali (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/DERBY-2616?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Mike Matrigali updated DERBY-2616:
----------------------------------
I noticed that netstat -a reported a lot of ports for the server were in TIME_WAIT, and I found that default TIME_WAIT on XP
is 240 seconds. I also found the following on the net about TIME_WAIT and am wondering if either the test or the server
is forcing a artificially small port space and thus causing this wait time:
TIME_WAIT is an integral part of TCP's correctness algorithms. It is
there to protect new connections by the same "name" from inadvertently
accepting segments from old connections and thus corrupting data.
Strictly speaking, TIME_WAIT is supposed to last as long as four
minutes, so the connection rate that could result in attempts to reuse
a TCP connection name (local/remote IP, local/remote port) that is
still in TIME_WAIT would be:
sizeof(portspace)/240
If your client application is allowing the stack to pick the local
port number (eg is not calling bind() to pick a port number itself),
then likely as not, the range of ports it gets will be 49152 to 65535
or ~16384 port numbers:
16384/240
or 68 connections per second.
The best "fix" is to get your applications to use long-lived TCP
connections. The next best fix after that is to broaden the number of
ports (and perhaps IP addresses) involved. One way to do that is to
have the application attempt to bind() to port numbers in the range of
day 5000 to 65535. That would increase the rate before attempted
TIME_WAIT reuse to
65000/240
or ~270 connections per second.
You could achieve similar results by spreading the traffic across a
larger number of IP addresses - on the client, the server, or both.
A much more distant fourth option is to decrease the length of TIME_WAIT to
say 60 seconds (math left as an excercise to the reader :)
However, you should "never" take steps to make there be no TIME_WAIT
state at all, such as using an "abortive" close.

Component/s: Regression Test Failure
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.

[jira] Resolved: (DERBY-2616) intermittent network startup related
errors in running junit nightly test suite
Posted by "Mike Matrigali (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/DERBY-2616?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Mike Matrigali resolved DERBY-2616.
-----------------------------------
Resolution: Fixed
Fix Version/s: 10.3.0.0
535572 checkin fixes this problem for my test running.
Increase the maximum wait time for tests that start the server. On my
windows XP system I would get intermittent failures at the old 60 second
max. I believe the issue is turnaround time on the port, rather than a
specific startup issue in the code. Setting the max to 300 seconds allowed
me to pass a complete nightly test and also passed a reiterated test 30 times
that would previously fail every time at the 60 second level.
