Writing interleaved data into a TDMS uses a ton of memory

[nanocyte]

I'm trying to write a 500kb of boolean data to disk but the write takes a long time (72 seconds) and I run out of memory and get this error:

Error -2500 occurred at TDMS Write in TDMS write test.vi

Possible reason(s):

LabVIEW: (Hex 0xFFFFF63C) Storage VIs internal error.

Setup:

LV2018

sbRIO 9627

The articles do not seem to be applicable because I'm not performing many small writes. It also doesn't explain the excessive memory use.
