First thing I’d do is to look at the client (fedora) journal for anything funky happening.

‘sudo systemctl status nfs-client’

Since it’s random I assume you won’t have any timeout in your /etc/fstab but it might be worth taking a look anyway.

Be aware that if the network drops the NFS will be disconnected and won’t auto-reconnect so this could also be the issue.

I don’t know if it plays well with container mounted volume, but looking at autofs could be a solution to auto-remount the share. I use it profusely for network mounted home directories.

Can confirm. Was quite unhappy in my mechanical engineering job, had an opportunity to develop something nice in python, was told we’d do it in excel/vba instead, still unhappy.
