Hi Babis, Looking at the version of your Virtuoso Server 06.02,3128 from Sept 2010, it would appear you are a commercial license holder/user for which the latest available builds are 06.02.3129, 1.4 & 3.57 from March 2011, so I would recommend you upgrade your components to this latest version, which is available from http://download.openlinksw.com/virtwiz and is a free upgrade ...
