------------------------------------------
Also what is the value of '{{ulimit}}' ?
> Unbind breaks connection
> ------------------------
>
> Key: DIRAPI-342
> URL: https://issues.apache.org/jira/browse/DIRAPI-342
> Project: Directory Client API
> Issue Type: Bug
> Affects Versions: 2.0.0.AM2
> Reporter: Stefan Seelmann
> Priority: Major
> Fix For: 2.0.0.AM3, 2.0.0
>
>
> The DelegatedAuthIT/DelegatedAuthOverSslIT/DelegatedAuthOverTlsIT tests fail
> randomly (I try to stabilize tests on Windows, but also happens on Jenkins).
> They all do multiple bind() and unbind() on the same connection, it seems the
> unbind() is the reason.
> A simple test to reproduce the problem (on Linux):
> {code}
> @Test
> public void testSimpleBindAndUnbindLoop() throws Exception
> {
> try ( LdapConnection connection = new LdapNetworkConnection(
> Network.LOOPBACK_HOSTNAME,
> getLdapServer().getPort() ) )
> {
> for ( int i = 0; i < 10000; i++ )
> {
> System.out.println( i );
> connection.bind( "uid=admin,ou=system", "secret" );
> assertTrue( connection.isAuthenticated() );
> connection.unBind();
> assertFalse( connection.isAuthenticated() );
> // Thread.sleep( 10L );
> }
> }
> }
> {code}
> Without the unbind() or when sleeping for 10ms it works fine.
> Otherwise I saw 3 different errors:
> {code}
> org.apache.directory.ldap.client.api.exception.InvalidConnectionException:
> ERR_04108_INVALID_CONNECTION Cannot connect on the server, the connection is
> invalid
