I didn't know there was a replacement for the radosgw role! I saw in the ceph-ansible project mention of a radosgw load balancer but since I use haproxy, I didn't dig into that. Is that what you are referring to? Otherwise, I cant seem to find any mention of cive being replaced. For the issue below, I guess the dev was using a single threaded process that was out of control. They have done it a few times now and kills all four gateways. I asked them to stop and so far no repeats. For deletes, they should be using the bucket item aging anyways. -Brent -----Original Message----- From: Eugen Block &lt;eblock(a)nde.ag&gt; Sent: Friday, October 23, 2020 7:00 AM To: ceph-users(a)ceph.io Subject: [ceph-users] Re: Rados Crashing Hi, I read that civetweb and radosgw have a locking issue in combination with ssl [1], just a thought based on Since Nautilus the default rgw frontend is beast, have you thought about switching?
