      A DESCRIPTION OF THE PROBLEM :
      When running some java applications, all the available shm segments are used by java, causing problems in other shm enables apps.

      this happens to me using freeguide and in this url (https://bbs.archlinux.org/viewtopic.php?id=200184) you have other people with the same problem.

      Older versions didn't have this problem and as the url above downgrading "fix" the problem

      Not all java apps show this problem, but don't know why

      REGRESSION. Last worked in version 7u80

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Simply run the app, use it a little and the shm segments start to rise by checking the "ipcs -u"

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      just a few segments used
      ACTUAL -
      ipcs -u and ipvs -m show a huge amount of segments used by freeguid and some other java apps

      REPRODUCIBILITY :
      This bug can be reproduced always.

      CUSTOMER SUBMITTED WORKAROUND :
      close and reopen the java app
      or
      downgrade the java7 jre or upgrade to java8
