"using maximum file size" message

With the latest firmware I am seeing a "using maximum file size" message flash up on the screen for a few seconds when I begin recording. I had the Nanoflash set to; 140Mb/s, I-Frame, MXF and the maximum file size was set for 95%. I've skimmed though the latest manual and couldn't find any mention of this message. Can anyone enlighten me to it's meaning?

...so is this an error message that I should be concerned about or is it just a status message?

...is anyone else seeing this message at the start of a clip? Is it an indication of an incorrect setting that needs to be changed?

Hi Paul,
The nanoFlash/Flash XDR displays this message and sets the file size to 100% because of the higher bitrate you are using. With 140 Mbit and above, we automatically force the filesize to 100% to ensure there is plenty of time to close the file and open the next one. With higher bitrates, there is less time to do this. The longer recording time there is between each file allows the unit to catch up on the time lost closing and opening files. Eg if it takes 0.25 seconds to close/open the next file, the nano/XDR will need to catch up on that 0.25 seconds during the next file.
With lower bitrate (100 Mbit and below) we have enough time because the cards can write much faster than the 100 Mbit and makes it easier to catch up on missed time.

Any chance this can be tied to card speed instead of hard-coded?

Also, I'm more interested in limiting the file size in Bytes rather than % of maximum file size.
