> We experience problems with performing any operation (deleteall, get etc.) on
> a znode that has too many child nodes. In our case, it's above 200k. At the
> same time jute.max.buffer is 4194304. Increasing it by a few factors doesn't
> help. This should be either solved by limiting the number of direct znodes
> allowed by a parameter or by adding a hard limit by default.
> I am attaching some screenshots of the commands and their results. What's
> interesting the numbers from getAllChildrenNumber and stat (numChildren)
> commands don't match.
