Hi, Mark!

 From my knowledge, the "cachedb is empty" test is not available right now.

However, why not use either the recently added "raise_event" [1] 
function, or even a shared $shv(cache_reset) variable [2] as a pure 
"on/off" binary marker in order to hook into the opensips.cfg 
environment via MI interface and then instruct OpenSIPS to do a 
cache_remove_chunk() [3], followed by re-populating the cache?
