             Summary: ignoring message received from null session
                 Key: DIRSERVER-2369
                 URL: https://issues.apache.org/jira/browse/DIRSERVER-2369
             Project: Directory ApacheDS
          Issue Type: Bug
    Affects Versions: 2.0.0.AM26
            Reporter: Alexander Schwartz


In a test setup we regularly saw the warning that an unbind request wasn't processed (see log snippet below). This lead to errors later in our test, as it assumed that the unbind would have been successful. 

Looking at the comment in the code of LdapRequestHandler, it reads: "in some cases the session is becoming null though the client is sending the UnbindRequest before closing".

Our workaround attempt is now to enable Java's LDAP connection pooling so that we don't close the LDAP session right after sending the unbind request. 

Ideally we would like to see the unbind request being processes regardless of the closed session, as the caller doesn't really have means to determine if the asynchronous processing has completed.

It would be great if ApacheDS would handle this case.

 

The workaround for Java LDAP connection pooling:
 * com.sun.jndi.ldap.connect.pool set to true to enable connection pooling
 * com.sun.jndi.ldap.connect.pool.maxsize set to the same value  as com.sun.jndi.ldap.connect.pool.prefsize to avoid short-lived connections

 

The log:

{{11:05:56,830 INFO [org.apache.directory.server.ldap.handlers.LdapRequestHandler] (pool-26-thread-1) ignoring the message MessageType : UNBIND_REQUEST}}
{{Message ID : 3}}
