Processes hang if NFS connection is lost

[Jeremiah Bess]

Got an interesting issue been dealing with for over a year. I have an NFS server on my Raspberry Pi running Raspbian at home for our shared file storage. If I take my laptop off my home network without restarting my system, or my NFS server goes offline accidentally, any time I open my file manager or text editor on my Linux Mint 19.2 box, those applications hang and never start up completely. I have to unmount my non-functioning NFS connection, and then those apps will start.

I've tried using Automount for NFS, but that didn't work, so I've gone back to a direct NFS connection. Also tried the bg and soft nfs mount options, but those don't seem to help either. Any ideas what I should look for in troubleshooting this issue?

NFS server /etc/exports:
/mnt/hda 10.0.0.0/24(rw,no_subtree_check,anonuid=1000,anongid=1000)

Linux Mint /etc/fstab:

10.0.0.2:/mnt/hda /mnt/server nfs rw,bg,soft 0 0
