Here's a simple code that reproduces it: #include int main() { FILE *f = fopen ("/bar", "w"); fclose(f); return 0; } Conditions to reproduce it: - The resulting binary must be executed from the nfs mount - The binary must be built after mounting the NFS share. I haven't tried building it on a different host, I don't have access to multiple RPis. Also, if I build the binary, umount/remount the NFS mount point, which has the binary, execute it, then it works. I've also tried this with the raspbsd.org's image, I could reproduce it as well. Another interesting thing is, when I first booted the RPi up, the NFS server was a 10.2-STABLE, and later got updated to 11-STABLE. While it was 10.2 I've tried to build some port, and I don't remember having this issue. So, could someone please help me figure this out and fix it?
