I am testing the latest version of GCE - 6.0.3. I installed it in ESXI 5.5 and virtualbox 6.0.12.
In both cases I allocated 6GB RAM, but the GCE doesn’t see it and don’t use. In the ESXI version I can see only 3GB in shell, in VirtualBox - 3.5GB.
When I try to scan some subnets, a lot of log errors about not enough memory and after there is no any update in the WEB interface for scan status, like it is stuck on 4%, at the same time from the full.log file in the shell I see that the scan is running. But of cause this problem is just a consequence of the memory allocation problem.
So, the question, is this some known limitation of GCE? But strange because in the requirements it is written that it should have minimum 4Gb of RAM.
That is a limitation on the Community Edition, if you need more power you need to buy a Greenbone (Virtual) Appliance, or build your own source edition with no support. Please keep in Mind the GCE is a free offering for Small Office and Home Environments.
