> 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.
