I can – somewhat happily – confirm that setting debug_rgw to "20/1" makes the issue disappear instantly. Even if the RGW is in the middle of a "stuck" listing, the debug level change causes the load to drop and results appear on the client almost instantly. After setting debug_rgw back to "5/1" the listings get stuck again, which in our case is not just occasionally, but always and for every bucket. Not exactly a solution, since we're already having some trouble keeping the docker container logs to a manageable size, but might be good enough as a workaround.

Not sure how we can find out steps to reproduce the issue in the first place. Happy to do some testing if anyone has suggestions. Also, I'm inclined to report this as a bug at this point unless there's opposing advice.

Thanks,
Stefan
