Hello everyone!
Sorry for my English.
I installed the nfs service a few months ago, but never used it. When trying to use this week, an error will be reported at sometime:
like this:

.
When this happened, I use 'kill' and 'kill -9', but it didn't work.
I tried 'systemctl restart nfs-server',it didn‘t work.
I used 'pacman -Syu' every week， So，I don’t know after which update the failure occurred.
My computer and software:
AMD 3970X,Gigabyte TRX40 AORUS
64G RAM
kernel:5.8.5-arch1-1
amd-ucode:20200817.7a30af1-1
nfs-utils:2.5.1-1
Thanks！
