Hey Dan,

We've got three rgws with the following configuration:

We're running 12.2.12 with civit web.
3 RGW's with haproxy round robin
32 GiB RAM (handles = 4, thread pool = 512)
We run mon+mgr+rgw on the same hardware.

Looking at our grafana dashboards, I don't see us running out of free memory, they hover around 5 GB free (but sometimes lower).

From my quick tests (a fair while ago) I found making more handles eventually lead to OOMs.

Currently, we've been getting some "connection reset by peer" (errno 104)... from client reads, which I suspect is due to the low handles setting.

We plan to move the rgws onto 125 GiB beefier machines.

Cheers,
Tom

Hi all,

Does anyone have a good config for lower memory radosgw machines?
We have 16GB VMs and our radosgw's go OOM when we have lots of
parallel clients (e.g. I see around 500 objecter_ops via the rgw
asok).

Maybe lowering rgw_thread_pool_size from 512 would help?

(This is running latest luminous).

Thanks, Dan
