Dmitriy Govorukhin created IGNITE-9244:
------------------------------------------

             Summary: Partition eviction may use all threads in sys pool, it leads to hangs
send a message via sys pool 
                 Key: IGNITE-9244
                 URL: https://issues.apache.org/jira/browse/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 purpose.
