Hi all,

We observed a very high load on the hard disk while executing XA transactions, probably in the directory: 
jboss-as-7.1.1.Final/standalone/data/tx-object-store/ShadowNoFileLockStore/defaultStore/StateManager/BasicAction/TwoPhaseCoordinator/AtomicAction/

It is about 60 Mb/s (!!) when 150/s distributed transaction are performed. 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?
