Bitcoin Core 27 crash at sync - Ubuntu - No error in logs about bitcoin HOT 6 CLOSED

2Tb HDD for blockchain storage

What filesystem is the storage? Is it attached via USB? Is the datadir on the storage, or only the blocksdir? What is the full bitcoin config file?

Can you run it in gdb again for a traceback?

Does dmesg say anything?

Thanks for taking the time answering @maflcko.

The external HDD is mounted as a GUID Partition Table and is connected via USB3 to the motherboard's input. Only blocksdir is stored in the HDD.
The datadir is stored in the internal SSD

Attached the gdb output when running bitcoin-qt in the debugger: gdb.txt

Please also find the dmesg output: https://pastebin.com/WBVXnRYe

The gdb txt is empty. You can also post it in a comment, if it is shorter than 100 lines.

@maflcko apologies, here is the dgb extract https://pastebin.com/LQri1rtg

from bitcoin.

I mean it doesn't contain the crash information. Are you sure this is a crash and not a normal shutdown or someone initiating a shutdown?

In any case, if this really is a crash, you can get the traceback with something like:

gdb --args .../bitcoin-qt

...

> run

Then recreate the crash and check the output in the terminal.
