    Description

      We are testing master-slave configuration for ApacheDS and observed inconsistency when data from MASTER gets

      deleted. The record gets deleted from MASTER but does not get deleted from SLAVE. However this does not happen

      always. Secondly we are unable to find out the pattern for the same.

      We have seen this issue after executing the Test Cases in sequence.

      Scenario - Master changes state from RUNNING to STOP and then RUNNING again while Slave is in 'RUNNING' state
      Ensure that MASTER and SLAVE are running before executing each test case.

      ========================================================

      Test Case No: 1

      1) Stop Master
      2) Restart MASTER
      3) Add an entry to the MASTER

      dn: cn=amodkadam,ou=users,ou=system
      objectClass: person
      objectClass: top
      sn: kadam
      cn: amodkadam

      Expected Result :

      SLAVE should get corresponding entry for

      dn: cn=amodkadam,ou=users,ou=system

      Actual Test Result:

      Same as expected result.

      ===========================================

      Test Case No:2

      1) Stop Master
      2) Restart MASTER
      3) UPDATE an entry in the MASTER

      dn: cn=amodkadam,ou=users,ou=system
      objectClass: person
      objectClass: top
      sn: kadam_update
      cn: amodkadam

      Expected Result :

      SLAVE should have UPDATED entry for

      dn: cn=amodkadam,ou=users,ou=system

      Actual Test Result:

      Same as expected

      ================================================
      1) Stop Master
      2) Restart MASTER
      3) DELETE an entry from the MASTER

      dn: cn=amodkadam,ou=users,ou=system
      objectClass: person
      objectClass: top
      sn: KADAM
      cn: amodkadam

      Expected Result :

      Corresponding entry should be deleted from SLAVE but does not get DELETED

      Actual Result

      Fails and the record in the SLAVE does not get deleted.

      However this does not happen alwyas.

      =========================================================================

      Could you let us know what could be issue and how to fix it ?
