Jakub,

Well, good thing is that all 100 sessions (+900 later) were
replicated/backed up (by the BackupManager) to other cluster members that
host the same application --> 25+25+50 = 100 and 250+250+500 = 1000.

What happens if you repeat the experiment, but without one of the servers,
e.g. 28080?

Can you send your full cluster configuration? How are you starting you
servers? Do they start with the same JVM parameters (-Xmx and -Xms)?

Cheers!
