Comments
WORK AROUND

Set -Xmx and -Xms to the same value to avoid this problem
(but you might still run into the day one bug documented
in 6186200, which will be fixed later in Mustang).

EVALUATION

The code in 5101236 to avoid STW GC attempts when GC is locked
out, should have instead expanded the heap when possible.
