We recently updated to PHP SDK version 2.07 (on CentOS 6.6 & PHP 5.5.24 & CB Server 3.0.1 Community), and have not been able to use couchbase.config_cache since. We noticed this after seeing an increasing number of connections to the cluster.
We did find another post that mentioned the SDK config is no longer in php.ini, and it is now controlled in the query. We made this change, and we still have issues with the cache files not creating themselves so they can be used. Has anyone experienced this? Any known solution?
