Looks like the error originates with:

ERROR 2022-09-05 06:24:21,992 [shard 0] seastar - Could not setup Async I/O: Resource temporarily unavailable. The most common cause is not enough request capacity in /proc/sys/fs/aio-max-nr. Try increasing that number or reducing the amount of logical CPUs available for your application
