Bryan Pendleton commented on DERBY-1219: ---------------------------------------- Hi Deepa, nothing obvious has jumped out at me yet, but I will keep looking. Three questions: 1) You said you were able to reproduce this outside the harness; can you post a brief description of the steps, so that I can experiment with the code in my environment? 2) Were you running with sane=true, or sane=false? If sane=false, can you try sane=true? 3) You mentioned that the server does not get any data in DDMReader.fill, and thinks the client has disconnected. Can you expand on how you came to that conclusion? Were you able to see an IOException being thrown? Can you get a dump of that exception? After the exception has been thrown (i.e., during the hang), does netstat think that there is still an active TCP/IP connection between the client and the server? thanks, bryan > jdbcapi/checkDataSource.java and jdbcapi/checkDataSource30.java hang > intermittently with client > ----------------------------------------------------------------------------------------------- > > Key: DERBY-1219 > URL: http://issues.apache.org/jira/browse/DERBY-1219 > Project: Derby > Type: Test > Components: Network Server, Network Client > Versions: 10.2.0.0 > Environment: More often on jdk 1.5 or jdk 1.6 but hangs on jdk 1.4.2 as well > Reporter: Kathey Marsden > Priority: Minor > Attachments: client_stack_trace_050306.txt, drda_traces_050206.zip, > server_stack_trace_050306.txt, testfiles_afterhang.zip, traces_on_hang.txt > > The tests checkDataSource.java and checkDataSource30.java > hang intermittently especially with jdk 1.5. > Attached is the test run output and traces when the server is started > separately. > 1) Enable checkDataSource30.java by taking it out of > functionTests/suites/DerbyNetClient.exclude. > 2) Run the test with client. > java -Dij.exceptionTrace=true -Dkeepfiles=true -Dframework=DerbyNetClient > org.apache.derbyTesting.functionTests.harness.RunTest > jdbcapi/checkDataSource30.java > Attachements: > testfiles_after_hang.zip - Test directory. > traces_on_hang.txt - Server side traces obtained by starting the server > separately before running the test. > I wish I had time to work on this right now as I would really like to see > this valuable test in the suite, but hopefully someone else will pick it up. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
