             Summary: Partition eviction may use all threads in sys pool, it 
leads to hangs send a message via sys pool 
                 Key: IGNITE-9244
             Project: Ignite
          Issue Type: Bug
         Environment: 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
