Lots of inodes in /tmp/auth using service:jmx:remoting-jmx:// with username and password

Issue

• Every call using service:jmx:remoting-jmx:// with username and password seems to create a new file under <JBOSS_HOME>/tmp/auth with a .challenge file ending.
  The problem is that since we monitor the application using JMX, the maximum number of inodes on the machine gets exceeded really quickly. Is this a known issue ? What can we do to make JBoss clean this up/not create these files ?
• When using remoting-jmx with authentication, the tmp/auth directory fills up with .challenge files
