Large contiguous allocations have to occur during or soon after booting because of memory fragmentation. I can see that larger memory configurations on a 64 bit OS has a better chance of allocating big chunks like this. Make sure you have much more than 4G RAM since some hardware needs memory below 4GB, and the contiguous allocation at boot favors memory towards the top of the 4GB range. --Mark Tinguely. _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
