Hi all,
I'm using jboss 3.2.2 with the minimal configuration.
I've deployed successfully a stateless session EJB.
This EJB uses a simple class with cached objects (arrays of static objects loaded at start up time) to return objects to the ejb clients. All seems to work fine for some days,
but after this warning found in jboss server.log, jboss hangs :
[org.jboss.tm.TransactionImpl] Transaction TransactionImpl:XidImpl [FormatId=257, GlobalId=cupweb//22187, BranchQual=] timed out. status=STATUS_ACTIVE

Can anyone help me to debug this error ?
I don't use jdbc in in my ejb

Here is the simple ejb class :

public class CacheEJB
implements SessionBean
{
private SessionContext sessionContext;

public void ejbCreate()
{
}

public void ejbRemove()
{
}

public void ejbActivate()
{
}

public void ejbPassivate()
{
}

public void setSessionContext(SessionContext context)
{
sessionContext = context;
}

}
}

// private methods and attributes
