[jira] [Comment Edited] (DIRAPI-236) Unbind during search hangs

    [ https://issues.apache.org/jira/browse/DIRAPI-236?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14513188#comment-14513188 ]

-----------------------------------------------------------------

Here is another test: http://svn.apache.org/r1676138

More complex. One connection, two threads. One thread always unbinds and sleeps a bit. The second binds and then permanently searches, till the first thread unbinds. 

After some rounds there is only output to sysout from the "unbind thread: unbind", the serach thread hangs. In the thread dump I see the same as above.

If I use close() instead of unBind() the test is green.

> Calling LdapNetworkConnection.unbind() while iterating over an EntryCursor lets the iterator hang, either infinite (if timelimit is 0) or till the timeout occurs.
