The loading of the system I'm doing uses thousands of processes, which I can run more of with 512M than 1Gig. ie it fires off the processes slowly until it runs out of physical ram and then moves through swap when using 512M, with 1Gig, it freezes when it gets down to 350-255 megs free of physical ram. Tried juggling the new dimms around to different dimm slots, to no avail. I have a difficult time believing its a memory bus loading issue as this is ram thats actually been tested at tyan. Also have logs of vmstat -i -s -m and 'top' taken every second while loading up the processes before the system freeze, that show no apparent resource starvation going on. Any ideas?
