Hi hivarge,

You can effectively disable roster caching by creating a “cache.username2roster.size” property via the Admin Console and setting its value to 0 (zero). Be warned however, that this could greatly affect the performance of Messenger and increase the load on your database.

If you want to change the time between cache refreshes (which is what I would recommend doing) you can set the maxLifetime variable in the CacheManager to a lower value.

Hope that helps,

Ryan

in what units is maxLifetime expressed?

Hi Jerm,

The maxLifetime unit of measurement is in milliseconds.

As a slight side note, the cache api has been opened up quite a bit for the next version (2.6.0) of Wildfire, so doing things like clearing out a cache either via the Admin Console or a plugin will be possible.

Regards,

Ryan
