Kruk) Subject: [FreeBSD SNAP] Hard Memory error and paging Message-ID: <D2uDG9.FzK@undergrad.math.uwaterloo.ca> Sender: news@undergrad.math.uwaterloo.ca (news spool owner) Nntp-Posting-Host: barrow.uwaterloo.ca Organization: University of Waterloo Date: Mon, 23 Jan 1995 04:50:33 GMT Lines: 10 Hi all, I recently upgraded from 1.1.5 to December 2.0-SNAP with an awful degradation in overall speed which I think I have an explanation for. I have a bad page of memory. In 1.1.5, if memory serve (i'm not about to re-install it just to check) the boot-up code located the bad page and marked it as such. But the memory manager used all of the remaining memory, under and above the bad spot. In 2.0 it only uses the memory up to the bad spot, which is just a tad over 4 Meg. You can imagine how bad perfor is with only 4 Meg. Questions : Is this diagnostic correct ? Can I do something to get VM to use all the remaining memory ? Serge
