I came to the same conclusion last night.
After Microsoft’s Patchday (Win11), I wanted to adjust a VM.
This error occurred with 2 of my NAS devices.
Before installing the latest QTS/QuTS hero updates, everything was still working.
With another NAS, the error did not occur.
No errors:
TS-364, QTS 5.2.7.3297, VS 4.1.0.327, FileStation5 5.5.6.5018
NAS with the error
TS-364, QTS 5.2.7.3297, VS 4.1.0.327, FileStation6 6.0.3.7381
TVS-h674, QuTS hero h5.2.7.3297, VS 4.1.0.327, FileStation6 6.0.3.7381
By switching to FileStation 5, the error could be resolved on both NAS devices.
Note:
The error apparently only occurs since the QTS/QuTS hero update to version 5.2.7.3297 in connection with FileStation6.
