Hi guys,

I’ve a fairly complex I/O bound Erlang application.

Since yesterday, the beam.smp memory usage dramatically increased from
~160MB to something between [2.5GB,  3.1GB].
I’ve no idea how, nor why :-/

Attached is snapshot taken with recon_alloc:snapshot().
Please let me know if you want anything else.

Hope someone can explain me what’s going on.

Thank you.
