physical memory limit?

[Andreas Tobler]

Hi there,

is there an upper physical memory size limitation on ppc?

I play on a G3 imac with 1GB memory. On CURRENT. I often get SIGSEGV and 
a rebuild on that component succeeds. So, for me it seems strange. I'll 
change some DIMM's and see how far I get.
But nevertheless, I remember back in 05, I had to reduce hw.physmem to 
512MB. Is this still needed, Peter?

TIA,
Andreas
