Hi,

I´m using jboss3.2.3-tomcat4.1.29 in linux. I´m doing a stress test to my application. My application has an MDB that receives messages (1000-1500 during the 3 hours). Once a message arrives I call a stateless EJB that treats the message. In the stateless EJB I access some Entity Beans to upate DB and get some information to send a JMS message.
All the methods of the EJB´s have the tx attribute "required".
After 3 hours and incresing the number of users to 100 I get an error everytime that tries to access an EJB. The thing is that I access the EJB to do a read(findByPrimaryKey) and I get a timeout here. Almost all the time the same field is read. If I have lots of Entity Beans accessing this field, can this field be blocked ?

Here is the error I get :
