As someone who has worked with Ehcaches, I’ve also had to deal a lot with data eviction (meaning, the cache was down, got a miss on get, and now needs to retrieve data from the DB storage, but it’s full so it evicts some existing data). I just read a survey, according to which Ehcaches tend to be relatively small (usually 1-6 GB) compared to other data sets (1-20 GB), so this might be related to more frequent data eviction in second-level caches. The post discusses other Ehcache logging use cases (citing a survey on this issue by Teracotta Server): http://www.evidentsoftware.com/ehcache-logging-applicability-in-your-organization/. You might find it interesting. Stacey Hi Nicolas,
