Subject Re: backupManager - backup on all nodes and slowly
Date Mon, 03 Feb 2014 08:33:12 GMT
I have configured no loadbalancer,

I accessed tomcat directly

tomcats are on 18080, 28080, 38080, 48080,
In browser I used only 18080, this is my laptop test env, nobody else
access it,
28080, 38080, 48080, where untouched by broser, but in jvisualvm their
memory has increased by the same amount (about 100MB), it was increase
after gc .

Thx,
Jakub
