Why might my db be locked on starting bitcoin-qt after a clean shutdown and reboot?

# Why might my db be locked on starting bitcoin-qt after a clean shutdown and reboot?

(Asked by: username_0 on 2023-08-28)

I have LND v.16.2 running under Windows 10 with Bitcoin Core 23.0 on same machine.
When I need to reboot, I gracefully stop my LND node and close bitcoin-qt from the GUI, waiting until it has completely shut down. Then, when I try to restart bitcoin-qt after rebooting, it claims that the db is locked. Bitcoin-Qt is not running already, it is not in the autostart.
I have found that deleting the wallet.dat and creating a new one enables me to proceed. I am not worried about a financial loss, since the Bitcoin wallet contains no BTC, but it’s a yellow flag.
Can anyone explain why this might be happening and how I can prevent it?

Use Microsoft's Handle tool to see what files are open, and add the details to your question (You can limit the output to a specific folder or keyword such as 'bitcoin' by running the tool like this:
handle.exe E:\bitcoin

That will tell you all the files existing in E:\bitcoin that are open, and which process has them open.  That should allow you to narrow down what process is causing bitcoin-qt to report that error.
If handle shows no open files, then perhaps you have a permissions issue - i.e. maybe bitcoin-qt can't open the wallet.dat due to limited permissions.  Use icacls.exe e:\bitcoin to check permissions.
