Logs are getting spammed with stacktraces "WARN Error encountered while processing the incoming HTTP request: lemmy_server::root_span_builder: Unknown:"

My lemmy-ui container is spiking cpu usage and looking into the logs the following shows up (900.000 lines in total). Any ideas what the issue could be? I’m on 0.19.1, everything seems to be working fine aside from the logs filling up and the usage piking sometimes.
