siad crashes whenever trying to unlock wallet

[bitcoincoltd]

I'm running siad headless on a Digitalocean 512MB RAM node and every time I try to unlock the wallet it crashes siad.

curl -A "Sia-Agent" "localhost:9980/wallet/unlock" --data "encryptionpassword=mypassword"

The message siad gives before exiting:

Rescanning consensus set...
Scanned to height 46039...Killed

Increase ram or swap

Killed means that the kernel killed the process for using too much memory.

Sia needs a machine with at least 4 GB of RAM and 4 GB of swap.

4GB of RAM and 4GB of swap is insanely high for a headless daemon...

bitcoind uses more iirc

This will likely be addressed when we make improvements to the wallet. Still, 512MB of RAM may cause issues since we use multiple mmap'd Bolt databases.

I would say 2 & 2 is plenty, even when running the explorer. Which reminds me: Check the -M switch for siad and disable modules you dont need.

If you really want to run it on a digitalocean droplet you may get away with just setting up 4 GB of swap. But remember that that will make Sia very slow. Luckily DO is SSD based so it will still be usable.

Added a 6GB swap and that works to unlock the wallet (looking at the memory usage 1GB of swap would probably have been enough)

[Fornax96]

When you start uploading files it will start using more.

Back with version 0.5 I added 6 GB of swap too and it still ran out of memory, but that may have improved since then. I have not personally tried to run 1.0 on digitalocean yet

EDIT: Looking at my own siad instance it's using about 2.5 GB, and that is while it's uploading and hosting, so it's definitely better. Adding 3 GB swap would probably have been enough

Closing since the issue doesn't really concern the Sia-UI and appears to have a work around.
