2. Partition exchnage future dumps objects only limited number of times. I would suggest to
switch to mode when we double the delay between dumps each time, but no more than 30min

3. If exchange worker is stuck at GridDhtPartitionsExchangeFuture.waitPartitionRelease then
unreleased partitions should be reported (same rules as of pt 2 apply)
