My setup was originally Bitcoin core 0.21.0, with IBD done long time back.
Now for some experimental purposes, I turned on txindex in bitcoin.conf and reindexing was happening for hours.
In mid of it, I stopped the process, upgraded to 22.0 and started ‘bitcoind’ again. I picked up re-indexing from where it was terminated before. But then when I did ‘bitcoin-cli stop’, it got stuck with the following logs:

I waited for 1-2 hour for it to properly quit. It didn’t. So I closed my terminal, wishing it shouldn’t be screwing up / corrupt the files!
Gladly it didn’t. I then increase dbcache to 4096 (with the hope of increasing the speed of reindexing) and started bitcoind again. Now I again tried terminating with ‘bitcoin-cli stop’ and again got stop with these logs:

2021-11-25T17:33:20Z FlushStateToDisk: write coins cache to disk (21179795 coins, 2965556kB) started
I am not afraid to kill the terminal, since the last line of the log says ‘Writing something to disk’. I waited for almost an hour now.
My system monitor doesn’t show bitcoind, it shows this process: b-shutoff, which is not doing any active Disk read / writes!
Is it safe to close the Terminal? I don’t want to do IBD again! Any measures I can take to avoid this (bitcoind not stopping) in future?
Thanks.
Edit:
It ended properly exactly after an hour, once I made this post:

I am glad. But any hints to improve this situation?
