If you have moved to CF11 update 18, or plan to, note that there is a known bug affecting use of query caching, such as via the cachedwithin attribute of cfquery, causing it to sporadically return incorrect results.
Some good news is that Adobe has a fix available, in the form of special update jar you can obtain from Adobe, by emailing email@example.com to request it. You can refer to the bug report about this, cf-4204066:
As explained there, the update will of course be rolled into a later full update (no date set yet).
Some may wonder are whether the issue affects cf2016 or 2018, but it seems it does not. It’s also curious that update 18 would have introduced this, when it was meant only to address a security issue common to all 3 current cf versions.
Anyway, hope this is helpful to those using cf11 and running update 18.
