Hi @lidavidm, thanks for your reply! The culprit of this issue is that we
set `initReservation` to `Long.MaxValue` in one of child allocator.
```
rootAllocator.newChildAllocator("FileWriter", Long.MaxValue, Long.MaxValue)
```
If I changed the `initReservation` to 0. I don't see the `RefCnt has gone
negative error` anymore.
I'm still wondering how it relates to the issue. What's the best practice to
configure the initReservation parameter? Do we always set it to 0?
