---------------------------------------
> apacheds dump command - hangs very frequently
> ---------------------------------------------
>
> Key: DIRSERVER-682
> URL: https://issues.apache.org/jira/browse/DIRSERVER-682
> Project: Directory ApacheDS
> Issue Type: Bug
> Affects Versions: 1.0-RC3
> Environment: apacheds1.0-RC3
> Linux 2.4.20-8smp, 2CPU HT, jdk1.5.0_07
> Reporter: Ajay Upadhyaya
>
> I'm trying out apacheds1.0-RC3
> here is my env details
> Linux 2.4.20-8smp, 2CPU HT, jdk1.5.0_07
> I've a custom schema extension defined (works fine), and a data partition.
> ADS is working fine. When I try the dump command using apacheds-tools the
> dump is produced sometimes successfully (there are 2227 entries in the
> exported file... so its not huge), but many times the command just hangs.
> This happens when there are no queries done against apacheds by any client.
> Jstack shows blocked threads, thread dump is shown below. I looked around for
> this type of issue, and found this unresolved issue
> http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=5104239, but it was
> reported against 1.4.1, Anybody faced this issue, or have any insight...not
> sure if this is an issue with sun jvm or ADS code.
> The command I'm using is this
> (root)/usr/local/apacheds-1.0_RC3/bin#./apacheds-tools.sh dump -i
> /usr/local/apacheds-1.0_RC3 -p etouch -f /home/wikireg/dump
> this is how my apacheds-tools.sh looks like.
> #!/bin/sh
