--------------------------------------------------------------
Hello,
We are using JBoss Cache to cache our entities in a clustered JBoss Environment (with 6 nodes mostly. sometimes use 8 nodes). We have JTA configured and most of our ENTITIES are cached in transactional strategy. But there is this one entity that is cached in read-only strategy.
This Entity is mapped to kind of a key/value pair table with just 2 columns (key and value). We maintain this entity in read-only cache intstead of transactional mode because the values in this table are being accessed multiple times. We also performed some JMeter load tests on our application and proved that transactional mode was expensive than readonly.
As this entity is marked readonly, whenever the value of one of this entity is changed, we have a inbuilt framework that does a evict on this entity on all the other JBoss nodes. This way we ensure that the value of the modified entity is the same across all nodes. But here is where we are getting a org.jboss.cache.lock.TimeoutException. If my understanding is right, this exception is thrown as all the JBoss nodes are trying to acquire a lock on the node at the same time when our inbuillt framework tries to evict the node.
To add - we use the default mvcc-entity cache config

*Code :*
{code} HibernateUtil.getSessionFactory().evict(ApplicationProperty.class, aPropertyKey); {code}
The above code is being executed by all 6 JBoss nodes simultaneously.
Please provide your thoughts and appreciate if you can help fixing this. I would be glad to provide more info if I have missed any.
Thanks!
