Broker hangs reading KahaDB data store
--------------------------------------
Key: AMQ-2721
URL: https://issues.apache.org/activemq/browse/AMQ-2721
Project: ActiveMQ
Issue Type: Bug
Components: Broker
Affects Versions: 5.3.1
Environment: Red hat enterprise
Reporter: Dennis Klinkott
Broker hangs on loading the data store. Happens after using the broker for 10
hours in productive environment.
In broker log the last entries we see is a bunch of loading kahadb debug
entries.
2010-05-05 16:06:19,462 | DEBUG | loading | org.apache.kahadb.index.BTreeIndex
| main
But the broker doesn't stall completely. It is doing something with high cpu
load. But it doesn't get the data store loaded. Even after a few hours it
doesn't get finished (usually only takes a few seconds).
I took a few jstack-dumps where we can see the broker being busy putting
something into a hashmap.
We have 2 brokers connected as network of brokers.
