> ------------------------------------------------------------

> Key: OAK-6303
> URL: https://issues.apache.org/jira/browse/OAK-6303
> Project: Jackrabbit Oak
> Issue Type: Bug
> Components: blob, core
> Reporter: Julian Reschke
> Assignee: Thomas Mueller
> Priority: Major
> Fix For: 1.12
>
> Attachments: OAK-6303-test.diff, OAK-6303.diff

>
> It appears that depending on actual cache entry sizes, the {{CacheLIRS}}
> might grow beyond the configured limit.
> For {{RDBBlobStore}}, the limit is currently configured to 16MB, yet storing
> random 2M entries appears to fill the cache with 64MB of data (according to
> it's own stats).
> The attached test case reproduces this.
> (it seems this is caused by the fact that each of the 16 segments of the
> cache can hold 2 entries, no matter how big they are...)
