[erlang-questions] apparent memory leak in OTP 17

[Sverker Eriksson]

The statistics says there are a *lot* of poorly utilized carriers 
(mmap'ed regions)
waiting (in mbcs_pool) to die or be revived.

Do you have any notion about the previous peak memory load of the node?
Has it been loaded with hundreds of Gb with binaries?
