Vidyashree created AMQ-6663:
-------------------------------
Summary: IO exceptions causing Broker Service shutdown; When broker restarts, active-mq ignores the configured location for kahadb
Key: AMQ-6663
URL: https://issues.apache.org/jira/browse/AMQ-6663
Project: ActiveMQ
Issue Type: Bug
Components: Broker, KahaDB, Message Store
Affects Versions: 5.11.0
Reporter: Vidyashree
Priority: Critical
ActiveMQ version: 5.11.0.redhat-620143
A-MQ configuration in activemq.xml

Problem description:
During durable subscription removal, we are observing IO exceptions as below, and it is resulting in shutdown of the broker. And we also observe change in path of the kahadb location to the active-mq default location({$home}/activemq-data/activemq-instance1/KahaDB). It should have taken the configured location from activemq.xml

1. Why did ActiveMQ consider the default location for KahaDB (Mentioned in IOHelper and MessageDatabase classes of activemq) instead of the configured path during broker restart?
2. When we restarted the system with the affected contents of kahaDB store, we found the below information from the active mq log
org.apache.activemq.store.kahadb.MessageDatabase WARN (MessageDatabase.java:open:382) [main] [1] | Index corrupted. Recovering the index through journal replay. Cause:java.io.EOFException
org.apache.activemq.store.kahadb.MessageDatabase DEBUG (MessageDatabase.java:open:384) [main] [1] | Index load failure
- What could be the cause of index corruption?
- What happens if there is index corruption in the KahaDB store and system does not restart?
- We did not see any issue with disk such as disk is unavailable of no more space on the disk. So, in these conditions, how did the corruption happened in the system?
Is it related to https://issues.apache.org/jira/browse/AMQ-6086?
