Ole Ersoy commented on DIRSERVER-942:
-------------------------------------

OK - I retested this.  First I commented out the "testDeleteNonExistingSyntaxSchemaEntry" test.  Everything runs fine.  Then I ran it with the testDeleteNonExistingSyntaxSchemaEntry test.  The server freezes.  I ran it in debug mode, and here's the output from the console:

[15:26:44] WARN [org.apache.directory.server.core.DefaultDirectoryService] - You didn't change the admin password of directory service instance 'default'.  Please update the admin password as soon as possible to prevent a possible security breach.

After this output the server

Here's the test code just in case it's helpful (I just copied the JNDIConnectionTemplateTest from the testing archetype and pasted the code from the attached test):

>          Components: ldap
>    Affects Versions: 1.5.0
>            Reporter: Ole Ersoy

>
>         Attachments: CreateSyntaxEntrySelfContainedTest.java

> This is related to https://issues.apache.org/jira/browse/DIRSERVER-935
> By accident I tried running some code that deletes (935 looks up)
> entries that are not present.
> The server froze and I could not connect with LS
> anymore.
> First I assumed it crashed, so I tried doing
> ./apacheds start
> But I still could not connect
> so I tried doing 
> ./apacheds stop
> ./aapcheds start
> and back to normal.
> I need to code a self contained test for this.
> Cheers,
