Comment 27 for bug 1512760

I launched an IP-KVM java applet and here what I see:

$ sudo ipcs -m -p | awk '{print $3}' | sort | uniq -c | sort -n
      1 1408
      1 1526
      1 cpid
      1 Memory
      2
      3 1778
      3 1898
      3 3856
    780 4339
$ ps www 4339
  PID TTY STAT TIME COMMAND
 4339 tty2 Sl+ 1:17 /etc/java-config-2/current-icedtea-web-vm/bin/java -Xbootclasspath/a:/usr/share/icedtea-web/netx.jar:/usr/share/icedtea-web/plugin.jar:no -classpath /opt/icedtea-bin-7.2.6.1/jre/lib/rt.jar sun.applet.PluginMain /run/user/1000/icedteaplugin-puleglot-1pHWZM/4332-icedteanp-plugin-to-appletviewer /run/user/1000/icedteaplugin-puleglot-1pHWZM/4332-icedteanp-appletviewer-to-plugin /run/user/1000/icedteaplugin-puleglot-1pHWZM/4332-icedteanp-plugin-debug-to-appletviewer

The number of shared memory segments used by this java process constantly grows:

$ sudo ipcs -m -p | awk '{print $3}' | sort | uniq -c | grep 4339
    839 4339
...
$ sudo ipcs -m -p | awk '{print $3}' | sort | uniq -c | grep 4339
    865 4339

The default limit for a number of shared memory segments:

$ sudo sysctl kernel.shmmni
kernel.shmmni = 4096
