That was me, since you specifically asked somebody to try to use up all RAM. I did this right when David was trying to upload worksheets. This was by using the matrix(ZZ,10000) command (or something like that). You might recall that I specifically said in this thread that I was doing so. > Sage was the only program running in the zone, so perhaps Sage running on > Solaris is using up an excessive amount of resources for some reason.
