BKF files grow beyond the maximum size
I have two B2D folders that is located on two different NAS (made available through share).
When I created B2D folder I set default 4 GB maximum size for backup-to-disk files.
Both B2D folders are combined in a one device pool.
I use this pool only for duplication in several jobs.
At any given time, only one NAS is connected (B2D folder).
Disconnected NAS (B2D folder) is paused and all duplication jobs executing properly to the pool with the other one NAS.
When I created the B2D folders initially everything was OK, during the duplication were created BKF files with correct size (max 4 GB).
When I disconnect the NAS for a month and connect again after this period (uncheck pause for this B2D folder) the BKF files grow overe maximum size.
BKF files that have grown over the limit their "Total capacity" are more than 4 GB (most frequently equals the size of the file).
I decided to delete all BKF files in this B2D folder. I started the task duplication and new BKF files have exceeded maximum size.
Now the "Total capacity" for BKF files shows the 2 TB or 3 TB (this corresponds to the capacities of NAS).
The entire job duplication is thrown into a one BKF file instead to multiple BKF files.

All duplication jobs are based on policy with duplication template. In duplication template in "When this job begins" is set "Overwite media" and destination media set is set with: Overwite protect period - 6 days, Append period - Infinite - Allow Append
Can anybody steer me, what is the reason for this behavior?
