I figure out what's the exactly problem.
In server/xxx/conf/bootstrap/bindings.xml I founded that
<!-- JBossTS Transaction Status Manager -->
<bean class="org.jboss.services.binding.ServiceBindingMetadata">
<property name="serviceName">TransactionManager</property>
<property name="bindingName">transactionStatusManager</property>
<property name="port">4713</property>
</bean>
And the port 4713 is already used by PulseAudio, so I changed the port in the Jboss configuration and everything works ok.
