> Issue Type: Bug

> Reporter: Maciej Lisiewski
> Priority: Minor

>
> Hunspell stemmer requires gigantic (for the task) amounts of memory to load
> dictionary/rules files.
> For example loading a 4.5 MB polish dictionary (with empty index!) will cause
> whole core to crash with various out of memory errors unless you set max heap
> size close to 2GB or more.
> By comparison Stempel using the same dictionary file works just fine with 1/8
> of that (and possibly lower values as well).
> Sample error log entries:
