I think you have a problem in your hibernate mapping or config file, in case the existing problem in your mapping file is more probable. i think it doesn't related to Jboss AS. that's a problem in Hibernate domain. pay attention to "org.hibernate.cfg.HbmBinder] Mapping class"
Announce me if you find a solution, if that i mentioned is incorrect.
What have you done so far to find out what is going on during that 9 minutes? What monitoring or debugging have you done?
Yes i put hibernate in debug level and between these two registers it only search for dtd file to validate the
Linkcontent.hbm.xml file nothing more.
The strange is this only happen sometimes no always, at the level of O.S we have registered a medium/high
iowait but no reason for that to CPU and Memory levels are normal expect for the iowait.
Thanks for feedback
So what you are saying is that the CPU use was not high. This probably eliminates a processing loop within Hiobernate. But there is a high iowait, which means that most likely Hibernate was waiting for something. The next thing to do is take some thread dumps during that time period to see what it is waiting on (disk, network, etc.).
