Well once you remove the oldhost from all of your proxy-server.conf's "memcache_servers" list in the their [filter:cache] section; and restart those services - they won't make any more connections to the unreferenced memcached server. Internal proxy might... you should double check your /etc/swift/object-expirier.conf's [filter:cache] section.
But if they did, I don't see why they would report a timeout if the old server was in fact accepting connections on 11211 - those two pieces of information don't seem consistent? Quite strange... -Clay On Thu, Apr 10, 2014 at 9:59 AM, Stephen Wood <[email protected]> wrote: > I'm wondering why the swift proxy hosts will keep memcached connections > open to other hosts even after I remove the memcached settings from the > proxy-server.conf and restart the service. > > I'm seeing what is the equivalent of ghost connections in the logs.
