Cache results being prefetched before the Cache Expire timeout.

Hello There,

Usually the Prefetch of cache results happen only when the Cache results expire. we have one Flow service having the below properties and the prefetch is happening so frequently say approximately 50 times after 4 hours of reset the service cache (using developer).

Cache Results = true
Cache Expire = 1440
Prefetch = true
Prefetch Activation =1

and also watt.server.cache.flushMins=1440. and

Does the prefetch of cache results happen only after cache expire or any other activity also can trigger prefetch of cache results? Any clue of why these many prefetch’s happening?

Many Thanks,
