[jboss-user] [EJB/JBoss] - Hanging JBoss - invoked while multiple threads active within

[flipmind]

I got this exception and a hanging JBoss on a production site. Here is the last entries in the log: - 

12:03:03,012 WARN [ValidatorResources] Form 'ProductForm' not found for locale 'en_NZ' 
12:07:41,977 WARN [arjLoggerI18N] [com.arjuna.ats.arjuna.coordinator.BasicAction_58] - Abort of action id -3f57fdff:12dd:466f4b3f:94029 invoked while multiple threads active within it. 
12:07:41,977 WARN [arjLoggerI18N] [com.arjuna.ats.arjuna.coordinator.CheckedAction_2] - CheckedAction::check - atomic action -3f57fdff:12dd:466f4b3f:94029 aborting with 1 threads active! 

It did not work until I restarted it. I don't know how to replicate it as it is the first time I have seen it. It may have occured at the same time as a user triggered a call to the loadCache() method of this EJB: - 

@Stateless 
@TransactionManagement (TransactionManagementType.CONTAINER) 
public class EStoreServerCacheManagerBean implements EStoreServerCacheManager, EStoreServerCacheManagerLocal { 
/** 
* Called when the cache needs to be refreshed from the database 
*/ 
@TransactionTimeout(value=600) //10 Minutes to load all the summaries 
public void loadCache() { 
logger.debug("loadCache called"); 
Store[] stores = storeManager.getStores(); 
for(Store store : stores) { 
EStoreObjectSpace.loadCache(store); 
} 
                      } 
} 

EStoreObjectSpace.loadCache() is defined as: - 

public static synchronized EStoreCache loadCache(Store store) { } 

Could it be that this method is synchronized ? 

Does any one have any recommendations for debugging this?
