Subject [jira] Commented: (DERBY-3795) BlobMemTest fails for network client with OutOfMemory errror with 16M heap
Date Thu, 24 Jul 2008 19:51:31 GMT

    [ https://issues.apache.org/jira/browse/DERBY-3795?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12616612#action_12616612
] 

Kristian Waagan commented on DERBY-3795:
----------------------------------------

Which JVMs have people tried this with?

I can reproduce this most of the time with Sun JVM 1.4.2. I have observed both failures; 2
errors and 4 errors.
With Sun JDK 1.5.0 and Sun JDK 1.6 I haven't been able to provoke the errors.

> The test memory.BlobMemTest should run with 16M heap, but now gives an OOM exception
for client. This appears to be a regression in the client driver.
