Hi @philippe-camelio_3885 ,
You mention the server is crashing? That's really strange, and we've never quite seen anything like this before. We routinely test on much less powerful hardware in nearly identical scenarios that you are doing now.
SQL Server / .NET will use as much ram as it can, so the usage isn't surprising or really concerning.
Otherwise we don't really any info info on the errors --- You'll need to track down error messages from the ProGet side of things; perhaps the Docker container error logs, the SQL Server error logs, etc. Maybe try putting the npm client (i.e. BuildMaster) on a different server, just to help isolate any potential issues.
We've seen a lot of weird things happen -- every now and then, there's a problem with the network controller/hardware/driver on the server, and it's having a hard time processing the 1000's of simultaneous "loopback" connections that npm is making from the BuildMaster container to the ProGet container, and the "outbound" connections that npm would be making to npmjs.org.
But until you find out what those errors are on the ProGet side, it's impossible to guess.
