We used to see this when we were running our own 2.4.24 kernel builds from
kernel.org. I can't find the exact errors anymore, but I think we saw (at
least) the 0-order error.
We've now moved to RHEL 3 and things are running fine
with no memory errors.

I don't think we saw JFS go read-only in this case,
but eventually the systems would become unresponsive and we were agressively
rebooting for a while.
