NT crashed while download data at startup of IBG connection

[BrainSailor]

Hi,
I was starting NT as usual on Sundays. I use the latest NT version with the recommende IB Gateway version.
NT started to download data as it always does at the startup of the connection with IBG. During that download it crashed with the following message in the trace file:

2021-12-12 17:26:39:083 *************** unhandled exception trapped ***************

The strange thing is that there is no 6A 03-21 in the workspace. I have the latest 6A 03-22 in the workspace. There is something wired going on.
Maybe someone wants to have a look at it.
Thanks

I just saw that you do not only download the last two days of historic data but also the whole history of a chart. I have a 6A chart which goes back 720 days. This explains the download of 6A 03-21.
But the question still remains: Why did NT crash and why are you downloading historic data so far back.
I have following options in the market data section:
Get data from server: false
Record live data as historic: true
Thanks
