One of our production PMGs also has just 4 GiB total memory, while > the other has 8 GiB but hovers around 3.8 - 3.9 GiB usage, so I really > do not see why we should increase the recommended memory to 6 GiB... 2.5 GiB as minimum should work as well (after checking a few systems with ClamAV running) - and I see the point of minimum meaning minimum as for the recommended - that depends a bit if you have other signatures enabled (securite raises this a bit), or another antivirus running - and if we want to cover that in the recommended setting - then I'd say 5G (if only to not have to change that again when clamAV signatures grow some more). _______________________________________________ pmg-devel mailing list pmg-devel@lists.proxmox.com https://lists.proxmox.com/cgi-bin/mailman/listinfo/pmg-devel
