06:07 <warren> I noticed a behavior of bitcoind, here's my guess of what's happening. Sync a new node with a huge dbcache=20000. That helps IBD to go a little faster. Hours after IBD completed systemd is told to shutdown. Shutdown sends a kill signal to all processes including bitcoind. bitcoind begins to dump everything to disk but it doesn't complete by 1 minute 30 seconds when systemd gives up and force kills everything before shutdown.

06:07 <warren> 2023-06-06T06:07:39Z Rolling forward 000000000000000000d243e447403fdfc3ae7ec260ee5356462b34188b9a15be (453346)

06:08 <warren> subsequent bitcoind it does this "Rolling forward" thing from block 1, I think this is some type of database recovery because the previous dbcache failed to flush to disk?

06:10 <warren> First of all, is my guess as to what happened correct?

07:41 <darosior> warren: sounds plausible. It can definitely take longer than 90s to flush a large dbcache.

08:08 <josie> warren: I saw similar behavior running with a dbcache=8000, though I think mine was exacerbated by running with --enable-debug
