This might be a wild stab in the dark, but we could try upping the amount of allocated memory by changing kconfig.xml.
Code:
Search "rootvm alloc=" (6 hits in 6 files)
300\kconfig.xml (1 hits)
Line 2: <rootvm alloc="786432,16384,98304,4096">
350\kconfig.xml (1 hits)
Line 2: <rootvm alloc="4341760,271360,196608,32768">
505\kconfig.xml (1 hits)
Line 2: <rootvm alloc="786432,16384,98304,4096">
600\kconfig.xml (1 hits)
Line 2: <rootvm alloc="1376256,65536,126976,16384">
650\kconfig.xml (1 hits)
Line 2: <rootvm alloc="4341760,271360,196608,32768">
950\kconfig.xml (1 hits)
Line 2: <rootvm alloc="3407872,65536,126976,16384">
Looking at these numbers, by the way, it seems to make sense that the 950 is the one having the most problems...
