We've implemented a workaround for this VMware issue in v7, so if you want to avoid such big values in latency counter you need to upgrade to the latest version of our Management Pack.
Besides this workaround, version 7 contains a lot of new cool features for VMware, such as new Operations Manager console widgets and dashbroads, vSphere HA status tracking and new ESX host security profile monitoring and many more. So I would absolutely recommend you to upgrade to v7. Keep in mind that there are several way to upgrade, so I would recommend you to check the upgrade instructions in the Installation Guide http://veeampdf.s3.amazonaws.com/guide/ ... LI%2FiA%3D
Feel free to ask any other questions regarding v7.
