> 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.
