Mails regarding this
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
