Description

Confirmed. The setting is the default shipped with the rpm; puppet-swift has no option yet to set this properly. Worst case is that expired objects are not deleted automatically. However, they will be unaccessible after they expired (as expected). Quickly checked this; even with a wrong memcached server the object-expirer will delete the expired objects. However, it's slower because of the non-working cache. Setting this to medium prio.

I just checked a default UC, afaict there is no process that uses expiring objects at all. Therefore the background process is basically doing nothing at all. Even if the process would be used, the setting is correct - the UC only consists of the localhost, and the memcached only listens on 127.0.0.1: memcach+ 13166 0.0 0.0 487612 9808 ? Ssl Mar07 0:25 /usr/bin/memcached -p 11211 -u memcached -m 6005 -c 8192 -l 127.0.0.1 -U 11211 -t 6 >> /var/log/memcached.log 2>&1 Therefore Swift must connect to 127.0.0.1. So both settings are fine IMO. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
