> Hi,
> > Could you open an Oak issue (subject for example "Diff cache entry too
> > large", at https://issues.apache.org/jira/browse/OAK) with this stack
> > trace please? I'm not sure how serious this is, given that it's only a
> > warning. But it should be fixed in Oak.
> it is not a serious issue. it simply means a diff cache entry will not be
> persisted to the capped "changes" collection in mongo. Oak will simply
> calculate the diff if an entry in that collection is missing or had been
> overwritten.
> nothing to worry about, but it would be good to have an issue to avoid the
> warning in the first place.
> regards
> marcel
