monerod "DB resize needed" causes full system hang

[xlae13]

I've had this issue actually across multiple versions, still on v0.18.4.4. This seems to be similar to #3845. I'll attach a debug file from gdb with the 'thread apply all bt' command as listed from the referenced issue. I would be more than happy to provide other logs and whatnot.

gdb.txt

Tried syncing the database on an old intel x86_64 thinkpad which worked flawlessly. The same cannot be said for my amd r9 5900x system. I tried the pre-packaged v0.18.4.4, and even building the debug version from source- both hang on the db resize.

The pre-packaged binary locks up the entire system to which only fix is to force disconnect of power to the whole system. My M.2 ssd shows a lot of activity during the lag spike, despite no increase to the data.mdb file. The debug version I built from source has similar behavior, but doesn't freeze everything- albeit noticeable slow down.

Thanks!

What is your partition formatted as? Btrfs?

Yes, both systems are on btrfs.

I dont think monero likes btrfs

I have zero issues with monerod on my intel thinkpad with btrfs and a sata ssd, so it could be btrfs but it still doesn't make a lot of sense why my thinkpad is cruising through the db sync on btrfs...

As far as I know, btrfs should work with monerod but it's not ideal filesystem for best lmdb performance.
