> In the current implementation, GridDhtPartitionsEvictor reset partition to 
> evict one by one.
> GridDhtPartitionsEvictor is created for each cache group, if we try to evict 
> too many groups as sys pool size, group evictors will take all available 
> threads in sys pool. It leads to hangs send a message via sys pool. As a fix, 
> I suggest to limit concurrent execution via sys pool or use another pool for 
> this purpose.
