apacheds dump command - hangs very frequently
---------------------------------------------
Key: DIRSERVER-682
URL: http://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.
