Hello.
After I upgraded virtualmin gpl from 4.01 to 4.02 today, I noticed that in the main window the System Memory Usage information doesn't appear anymore.
Please check why this happens, if this is a bug or simply something that changed and I have to activate somewhere.
Thanks
This is a known bug that can happen when using OpenVZ and the burstable and max memory limits are the same. It will be fixed in the next Webmin release.
