Hi, This is all out of curiosity and just FYI. I noticed that most recent engine master on CentOS 7.7 now requires about 8 GB of memory to compile. Otherwise it will fail during GWT part. 6 GB - not good enough. Strange thing is about a month ago it worked perfectly fine for me on 4 GB. Also, I am running it on VM, so old rule applies: it is 8 gigs starting memory, not max memory. I wonder if someone had similar experience. Fedor
