WebSocket connection warnings

See original GitHub issue

Hello. I have the latest dockerized Serum Vial running on a 6 CPU and 16Gb RAM machine that works with a dedicated Solana RPC node querying for 143 markets data. There is a lot of WebSocket connection warning messages as mentioned below. I see they usually appear in 5-10 minutes after an instance starts. Is it a problem and what side I should tune to fix it (Solana RPC, Serum Vial, or connectivity between them)? Let me know if the full log may help. Thank you!

warn: WS send error: write ECONNRESET
warn: WS send error: write EPIPE
warn: WS send error: WebSocket is not open: readyState 2

warn: Out of order notification for PUBLISHED event: current slot 77095564, update slot: 77095564, resetting... {"market":"SRM/SOL"}

Hi, I had issues running on smaller machines as Solana RPC requires quite a lot of resources (memory as well) - right now I’m running on https://www.hetzner.com/dedicated-rootserver/ax101 (AMD Ryzen™ 9 5950X 16-Core, 128GB of RAM) and it’s very stable. WS send logs can be ignored I think (it’s client that connects to serum-vial dropped connection) Out of order notification could suggest you’re running out of resources, what’s your CPU usage?
