Mmmmm.... now I am wworried about upgrading to STABLE! ;) I can't
think of a reason why I am seeing what I am seeing - on 7.1-RELEASE
I am certainly icreasing the limits not decreasing them, yet I
am seeing it running out of memory on the larger limit.

Note that these machines have no swap - but then since the system runs fine
on a 4gig machine with 4 gig of sap, I made the assumption that if
the machine was expanded to 8 gig of real memory it no longer needs the
swap, as it now has as much real RAM in it as real+swap was before.

-pete.
