pEXRAM values look right to me:

(gdb) print m_pEXRAM
$1 = (u8 *) 0x7fff9e000000 ""
(gdb) print GetExRamSize()
$2 = 67108864

Any idea of what can I do to debug this further?

UPDATE: as I debug the allocs it looks like SHM memory is used which is limited to 64 GB by default in docker - will try to increase.
