Subject Re: child always re-validates object fetched from parent
Date Mon, 08 Jan 2018 04:13:46 GMT
Can you post the complete records.config from your child cache ?
If I had to guess, it looks like heurstics or fuzzytimer may be set too low ???
But if you provide  a company sanitized version of your records.config
that should give us a better understanding of your setup.
