Linux NFS clients work with an OpenBSD NFS server. But if there are no
NFS requests for more than 5 minutes, the NFS client often freezes
forever.
AFAIU, after 5 minutes of inacivity, Linux NFS clients
disconnect. Then, if they need to issue new NFS requests, they
reconnect and so on. It seems that closing the connection doesn't work
well with an OpenBSD server.
Here's the output of tcpdump (port 2049) showing the problem.
First, 10.0.0.43 (Linux NFS client) mounts the file system of 10.0.0.8
(OpenBSD NFS server), which is OK:

then, there are no requests. The client seems to send a probe every
minute. At this point, if a NFS request was sent, it would work
normally.

After 5 minutes with no requests (below), the client tries to close
the connection. OpenBSD doesn't seem to reply with a fin packet. At
this point the client freezes until the file system is umounted. New
requests generate no network traffic. Probably, the NFS client waits
for the connection to be fully closed because it needs to reconnect
with the same source port.

I've noticed that other NFS servers (macOS, Linux) reply with a fin
packet, and the connection is fully closed. The next NFS request
reopens the connection with the same source port.
This way of closing the connection seems specific to NFS. Ex., closing
the connection of nc(1) generates the expected tcpdump output with the
3 packets (closing initiator FIN, FIN reply, and last ACK).
Any hints where to look to try to fix this?
For testing, the easier is to use -current and a tiny machine running
Alpine Linux 3.19, kernel 6.6.10 in vmm(4). I tried running Linux on
real hardware, same result, so the problem is not in vmm(4). Tried a
different Linux distros (Debian), same problem. The problem is not
new (testes 7.4, same).
Interestingly, sometimes the NFS server manages to close the
connection (it sends the fin reply), so the freeze doesn't occur 100%
of the time, but almost every time on my systems.
