Hi , Thank you for your feedback . It seems the error related to the fstrim run once a week ( default ) . Do you have more information about the NBD/XFS memeory pressure issues ?

Some kernels treat the default as infinity, but there were some >=4.9 kernels that switched behavior and started defaulting to 30 seconds. There is also known issues with attempting to place XFS file systems on top of NBD due to memory pressure issues.
