Open-NTFS 3G driver crashes system

First of all many thanks for your enormous efforts on building this great firmware! Congratulations! I really enjoy it and I hope you will continue to support and develop this firmware in the long run.

I have 2022.5 K26ARM USB AIO-64K running on Asus RT-AC66U B1, but I assume it could appear on any hardware.

I have a 4,5TB HDD connected to the USB port and it works very well with Tuxera driver. This is a quick overview:

# mount

However, if I switch to the Open-NTFS 3G driver, the router crashes and reboots randomly.

To reproduce the problem, I use the Open-NTFS 3G driver, and after a few hundred GB’s operations, the problem appears. I have no information about how much data need to be transferred, or how much time need to pass to reoccur. As a user, I see all effects of the reboot (loosing connectivity, lack of services), but after a while everything comes back obviously. I am sure that it was a reboot, as logging into the router’s CLI, it shows a few second uptime value.

This is a minor bug to me, as Tuxera driver works well – however it could result in unresolved issues and bad experience for new users if they decide to go with Open-NTFS 3G driver. Maybe it is worth changing the default to Tuxera?

Please tell me, if you need more information.
