During memory dump analysis of Origam server it was found out, that SqlAdapterCache doesn’t have any replacement policy implemented, thus growing indefinitely during the server’s lifetime.
In computing, cache algorithms (also frequently called cache replacement algorithms or cache replacement policies) are optimizing instructions, or algorithms, that a computer program or a hardware-maintained structure can utilize in order to manage a cache of information stored on the computer. Caching improves performance by keeping recent or often-used data items in memory locations that are faster or computationally cheaper to access than normal memory stores. When the cache is full, the algo...
We should implement one. I suggest TLRU.

Agree if it seems to be a real issue (in case od adapter caching that would mean many users would only login once, leaving the cache growing).
So sliding expiration option would be appropriate here.
