JMS MQSERIES UNCOMMITTED MESSAGES

Question

Hi,
I am having some problems when working with JMS over MQSeries 5.2.
I am developing a program using JMS that tries to send messages to a MQSeries queue under unit of work. The program works rigth while the number of uncommited messages is not too high but when I try to send more tan 3000 messages the following error occurrs:
Message: javax.jms.JMSException: MQJMS2007: failed to send message to MQ queue
I was checking MQSeries Queue Manager configuration and I saw the maximum Number of Uncommited Messages in this Manager being this of 1000000 so the problem is not in this way. Apart of this, if a send all the messages without unit of work I do not have any trouble so far.
Can anybody help at this point?
Cheers
