problem with timeout on BeanLockTransactions.

[joshua.kolash]

I've been getting this error below running my application under high stress loads:

I want to change the value of timeout to somthing other than 5000, unfortunately I've looked through the jboss source code and found in
org.jboss.ejb.BeanLockManager.java
on line 37 int txTimeout = 5000;
Is there any way to set this value with an xml file? I plan on submitting a bug report as well.

You can increase the transaction time-out in jboss-service.xml under the conf directory under your server. But from the exception it lookslike jboss detected a dead lock and killed one of the transaction. Are you using entity beans ? If so please make sure the sequence of your datbase operations are in the same order. Please look at jboss documentation, they talk about when deadlocks occur and your options

Did you guys crack this problem. I am having the same problem using JBOSS 3.2.3, I am using CMP Beans with CMR.

17:21:44,762 ERROR [STDERR] EXCEPTION Application deadlock detected, resource=org.jboss.ejb.plugins.lock.QueuedPessimisticEJBLock@1b65439, bean=CartoColourEJB,id={displays toString method of EJB that caused deadlock, this is just the data output of the feilds}

PLEASE HELP.
