Each distributed transaction includes 2 XA resources: JMS (HornetQ with persistence) and database (MySQL with JPA/Hibernate). Disc space is not growing but we are worried about the delay in accessing the disc. Is this situation is normal? Is there anything I can do with it? -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/748158#748158] Start a new discussion in JBoss AS 7 Development at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
