Well, the original poster didn't mention whether he's tried to restore in
single or multiuser mode. This actually makes a big difference. On my RELENG_6
test system (csup-ped and rebuilt as of 24-Oct-2006) I still see that process
resource limits in singleuser mode are _way_ too low. Here is multiuser mode
root limits (as set in /etc/login.conf; system-wide limits are even higher as
I have kern.max{d,s,t}siz="1G" in my /boot/loader.conf):
root@test# limits
Resource limits (current):
cputime infinity secs
filesize infinity kB
datasize 524288 kB
stacksize 524288 kB
coredumpsize infinity kB
memoryuse 131072 kB
memorylocked 65536 kB
maxprocesses 512
openfiles 600
sbsize infinity bytes
vmemoryuse infinity kB
However when I reboot into the singleuser mode (boot -s from the loader
prompt), I see the following:
# swapon -a && mount -a && limits -B
Resource limits (current):
cputime infinity secs
filesize infinity kB
datasize-max 1048576 kB
datasize-cur 131072 kB
stacksize-max 1048576 kB
stacksize-cur 8192 kB
coredumpsize infinity kB
memoryuse-max infinity kB
memoryuse-cur 1016100 kB
memorylocked-max 1016100 kB
memorylocked-cur 338700 kB
maxprocesses 6164
openfiles 12328
sbsize infinity bytes
vmemoryuse infinity kB
I fail to see where those super-low datasize-cur and stacksize-cur get set
(the aren't in /.profile nor in /etc/profile nor in ~root/.profile), but
they could prevent using the memory-hungry application (I suppose I can call
restore a memory-hungry).
