[Opensim-users] Urban legends (Was :Configuring a multi-hosted grid)

[Justin Clark-Casey]

Yeah, I've tried a shared cache before and it seems to be okay.  It's a bit messy because multiple simulators may 
attempt to clean up the cache at the same time, which results in quite a few seeing messy "file not found" warnings, 
though these should not be harmful.

It's hard to know how to get around this problem without making the cache yet another process or doing messy things like 
designating only one simulator to actually clean up files.  I also think the cache needs a facility to limit by size 
(like every other cache in the known universe :).
