Thanks.
I actually ran into this myself a couple of days ago; I don't think
that I've checked the fix into CVS yet, but will do so soon.
The short version: some data structures that the GC uses are resized
dynamically as the heap grows and shrinks. The very short version
is that one of these data structures (used by the EGC) needs to be
made a bit bigger; it should be proportional to the size of "everything
except for the youngest generation", and that value can change even
if the overall "size of the heap" (what's currently mapped) remains
unchanged. The EGC page map needs to be "as big as it can get before
more memory is mapped", not "as big as it needs to be at the moment".
Often, the difference between these values is very small; the data
structures are allocated by mapping a few pages; most of the time,
the right number of -pages- get allocated for this EGC table even
if the right number of -entries- is underestimated. If too few pages
are allocated, the EGC will try to write to unmapped memory. That
has something like a 1 in 2K chance of happening, and it seems to
have happened to both of us within the last few days.
I'll try to ensure that the fio is in CVS. A crude, temporary
workaround is to turn the EGC off.
