Boost 1.61 is not a supported version of boost. There are some changes to boost thread management in 1.61 that breaks the cooperative multitasking in FC. Updating FC to work with Boost > 1.60 will take some time.

The format is uint64_t bytes. For seed/witness I would recommend 8 Gb. For a full node, 20 Gb. The default is set to 20 Gb.
