Subject [jira] Commented: (DERBY-3258) 'Unexpected row count: expected:<0> but was:<3>' in testReleaseCompileLocks
Date Sat, 17 Jul 2010 21:54:49 GMT

    [ https://issues.apache.org/jira/browse/DERBY-3258?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12889538#action_12889538
] 

Dag H. Wanvik commented on DERBY-3258:
--------------------------------------

I just saw this on trunk on OpenSolaris svn_142, in the variant similar to what Myrna did,
but mine failed on the assert on line 146 rather than on line 120. It appeared when I ran
the test in Knut's parallel tester using 6 threads on my dual core laptop (Lenovo T61p, 4Gb
ram).
When running th test standalone I do not see the error.
