Update... The command "doas mountd -d" enters debug mode and displays its normal updates as clients mount the share.
This is what I observed on a controlled environment of three "windows 10 pro" clients. The server had a single share: /path/to/folder -network 192.168.1 -mask 255.255.255.0 When mounting a share for the first time, Windows allows browsing the network to find the resource. This is what happens: 1. The client asks for the list of nfs resources; 2 the server shows a stream of accepted mounts, no warnings, no errors; 3. while 2 happens, the client shows a warning that the server is not responding; 4. when eventually the client returns the list of nfs folders, the server crashes. The above occurs systematically. Restarting the server and repeating the client steps lead to a new server crash. The only way to mount the share is to type in the path, without browsing. When the server crashes, the debug shows no warnings and no errors. R
