I had a similar issue this morning, while doing a large compile (qt4). I do
not have a debug kernel going, so I can't get a dump or anything, but I had
exactly the same error as above (a different total allocated, of course, but
in the same neighborhood). If this happens again, I'll get a debug kernel
compiled, but hopefully it doesn't. :-)
FreeBSD 8.1-PRERELEASE #0: Wed May 19 00:23:09 CDT 2010
root@ark.bluetonc.org:/usr/obj/usr/src/sys/ARK amd64
real memory = 4294967296 (4096 MB)
avail memory = 3852931072 (3674 MB)
mcj@ark ~ % sysctl vm.kmem_size_max
vm.kmem_size_max: 329853485875
Not a lot of info here, I know, but it's just another data point.
Thanks,
