Hi All, A new module has been added to V2.1.x and 3.0 HEADs called rlm_cache (written by Alan DeKok). This provides an in-memory (volatile) cache, that can store and retrieve attribute values for control, request and reply lists (at some point the 3.0 version will be able to handle all lists). This is definitely not a cure for slow or unstable databases/directories, but may help for some temporary outages, and has additional uses for things like accounting stream de-duplication/ratelimiting, and query/congestion reduction. I've added some basic documentation here: http://wiki.freeradius.org/Rlm_cache, and there's more in the default module configuration file. Post on the list if you can think of any additional features you'd like to see added. -Arran
