> This issue was observed when we recently did some tests with SSD based bucket
> cache. Similar thing was also reported by @stack and [~danielpol] while doing
> some of these bucket cache related testing.
> When we try to preload a bucket cache (in file mode) with a new file the
> bucket cache fills up quite faster and there not much 'failedBlockAdditions'.
> But when the same bucket cache is filled up with a preexisitng file ( that
> had already some entries filled up) this time it has more
> 'failedBlockAdditions' and the cache does not fill up faster. Investigate why
> this happens.
