Subject [jira] Closed: (DERBY-4173) java/lang/OutOfMemoryError" "native memory exhausted" received on z/OS for process launched to shutdown network server and launch the replication run in Suites.All
Date Wed, 06 May 2009 22:35:30 GMT

     [ https://issues.apache.org/jira/browse/DERBY-4173?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Kathey Marsden closed DERBY-4173.
---------------------------------

    Resolution: Cannot Reproduce
      Assignee: Kathey Marsden

Well since the machine has been restarted, I have not been able to make this occur.  The JVM
developer that analyzed the dumps seems convinced that the JVM was doing the right thing and
there must have been some unknown problem with the state of the machine, which remains a mystery.

Closing Invalid.

> I did not notice this happening with the 64bit jvm when I ran against 10.5.1.0 RC1 but
there is a chance that it occurred and I didn't notice beaause it does not actually cause
tests to fail for some reason.
