Subject [jira] [Reopened] (DERBY-5624) System can run out of stack space while processing DropOnCommit requests.
Date Wed, 22 Feb 2012 20:35:48 GMT

Myrna van Lunteren reopened DERBY-5624:
---------------------------------------


I'm reopening, because I saw a failure in my nightly test of largeDataTests suite, looks like
this test is now pushing past the # of open files supported for my account:

(emb)largedata.Derby5624Test.testDERBY_5624 java.io.FileNotFoundException: /local1/cloudtst/dev/src/NightlyBuildResults.2012-02-21/largeDataTests/fail/Embedded_40/Derby5624Test/testDERBY_5624/derby.log
(Too many open files)

I'll attach the full error stack trace, and the console output of the suite run.

> The system currently recursively calls xact.notifyObservers() from DropOnCommit.update().
 It does this because in some cases
> new observers can be added while processing the list of notifyObservers and those were
being missed before the change, causing
> Assertions in the tests and possibly files not properly dropped on commit.
> Multiple users on the Derby user list have had failures running SYSCS_UTIL.SYSCS_COMPRESS_TABLE(),
running out of stack track
> with a heavily recursive stack trace of the form (see more detail from these reports
in subsequent comments):
