Hello,

after upgrading our nfs-server from 4.9.75 to 4.9.78 group permissions stop working (for clients). If you need group permissions to access a file or directory, sometimes access is granted, but rather often denied. Often access to the same object is denied within seconds after access was granted in an earlier access. user permissions work fine.

Downgrading to 4.9.75 fixes the issue.

Any chance you can use 'git bisect' to find the offending commit?

And also, does 4.14 work properly for you? 4.15?

thanks,
