I have a program that sends thousands of messages to the queue (Input Queue) and I process them and put them in another queue (Output Queue).
After consuming certain no. of messages (12000 to 13500), the messages are only queued up in the Input Queue. They are not coming out.
I have set the mdb objects min pool to 15 and max pool to 30 in the standardjboss.xml for message-driven-bean.
Also I have checked the thread dump in jboss jmx-console (jboss.system -> type=ServerInfo -> threadDump). It showed all the 15 threads of the mdb are in RUNNABLE state.
