I proposed the following two patches to address the issue and improve this module beyond the current issue: - https://review.opendev.org/711220 (the fix) - https://review.opendev.org/711247 (the improvements) After these patches will be merged and the issue fixed we will blacklist the version 2.1.0 of oslo.cache and propose a new release with the previous fixes embedded. Do not hesitate to review them and leave comments. Thanks for your reading. Le mer. 4 mars 2020 à 14:16, Herve Beraud <hberaud@redhat.com> a écrit :

`dead_timeout` [1] looks more appropriate in this case.

What do you think about adding a mapping between `retry_timeout` [1] and `dead_retry` [2]?

I think our issue is due to the fact that python-memcached accept a param named `dead_retry` [1] which is not defined in pymemcache.
We just need to define it in our oslo.cache mapping. During testing we faced the same kind of issue with connection timeout.

Please be informed that oslo.cache 2.1.0 breaks oslo_cache.memcache_pool
Kolla-Ansible gate is already RED and a quick codesearch revealed other deployment methods might be in trouble soon as well.
This does not affect devstack/tempest as they use dogpile.cache.memcached instead.
The error is TypeError: __init__() got an unexpected keyword argument 'dead_retry'
