title: Jboss Messaging (jbm_tx) table growing
body: <p>I am using JBoss-4.2.2.GA with JBM 1.4 and I am seeing the jbm_tx table in the jmsdb schema on MySQL growing.  When I select from the table I can see that there is never more that 5 rows at a time in it.</p>
  
  <p>Why would the table grow to a size, on disk, of over 6GB?  When it did this, my application and database suffered extramly long query times.</p>
  
  <p>Is there any way to prevent the .idb file from getting so large?</p>
