Having trouble deploying and using Tigerbeetle -- needs io_uring

I'm deploying a service that uses Tigerbeetle to handle tracking financial transactions.

However, when I try to run my service that uses the tigerbeetle client, I get:

error(tb_client_context): 49360072845773278101607755070886542750: failed to initialize IO: SystemOutdated

Tigerbeetle uses io_uring exclusively for networking for performance reasons. I'm pretty sure that this is what it's complaining about, because io_uring is only available on Linux 5.5 and later.

Is io_uring available on Railway?

I've just checked and the kernel version in use is 6.1.0

Thanks for the quick reply! I went and looked up the code that is actually throwing this error: https://github.com/tigerbeetle/tigerbeetle/blob/3cd7cf4799f65c81ffbc36eda788b8b26fd7da72/src/io/linux.zig#L69

The full error message (which didn't show up in my logs for some reason) indicates that `seccomp` is disabling the io_uring syscalls. Tigerbeetle's docs for running in docker containers apply the `--security-opt seccomp=unconfined` argument, which makes those syscalls available. Is it possible to configure my service so those syscalls are available?

Sorry but we don't provide a way to change any security_opt configurations.
