> Concurrent bind and unbind of objects puts ADS in an inconsistent (unusable)
> state.
> -----------------------------------------------------------------------------------
>
> Key: DIRSERVER-1369
> URL: https://issues.apache.org/jira/browse/DIRSERVER-1369
> Project: Directory ApacheDS
> Issue Type: Bug
> Affects Versions: 1.5.4
> Environment: Windows-xp, JDK-1.5
> Reporter: Murali Krishna
> Priority: Blocker
> Fix For: 1.5.5
>
> Attachments: MultiThreadedTest.java, MultiThreadedTest.java
>
> Original Estimate: 120h
> Remaining Estimate: 120h
>
> This is with reference to a problem we faced when performing concurrent bind
> and unbind of objects with ADS-1.5.4 release build.
> Please find the java program at the bottom.
> Steps to reproduce:
> 1. Install apache_1.5.4 zip version of it and not the installer and change
> port numbers to 1389 and 1636 respectively.
> 2. Create a naming context ( JDBM partition) on the lines of dc=example,dc=com
> 3. Also create the entry dc=example,dc=com
> 4. Run the java program provided below.
> Actual Result:
> The console throws up numerous Naming Exceptions with message "[LDAP: error
> code 80 - OTHER: failed for Del request
> Entry :
> '2.5.4.3=adsadminpref_thread-11,0.9.2342.19200300.100.1.25=example,0.9.2342.19200300.100.1.25=com'
> : null]; remaining name 'cn=tdsadminPref_Thread-11,dc=telelogic,dc=com' " for
> each thread operating on a preference object.
> As a result, the server gets into an inconsistent state and unoperational.
> Expected Result:
> The server should continuously bind and unbind the java hash table object.
> What could have caused this and how do we correct this.
> Are there any specific configurations to be made in the server.xml.
> I tried modifying some of the attributes like syncOnWrite, syncOnMillis,
> maxThreads, cachesize and also rebind (instead of bind and unbind) in the
> java program , but in vain.
> This is very important for us and do help us in this regard.
