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.

Siemens makes NX. Catia is made by Dassaults. They compete for the same space in the market

It’s a software that is used extensively in aerospace and car industries. It’s also ludicrous how expensive the licenses are.

It’s hard to beat for completeness of functions but also for complexity.

Working with Catia is the other way around, no amount of documentation is complex enough that you really understand what something does or can do.
