This is the next DRBD-MC beta release 0.5.2. DRBD-MC is a Java GUI that 
helps to configure DRBD/Pacemaker/Corosync/Openais/Heartbeat clusters.

In this minor release one major bug is fixed, where in some circumstances the 
whole GUI starts to acquire large amounts of memory and hangs indefinitely 
during the initial start. This was introduced in 0.5.1 and it is not a 
normal behavior even for a Java program.

You can get DRBD-MC here:


You can start it with help of Java Web-Start or you can download it and 
start it with "java -Xmx512m -jar DMC-0.5.2.jar" command.
