I had a similar problem with shared memory.
I found an option in /sys/conf/NOTES.
I think it could help in your case, if u increase
% options MAXDSIZ=(1024UL*1024*1024)
% options MAXSSIZ=(128UL*1024*1024)
% options DFLDSIZ=(1024UL*1024*1024)
apropriately.
E. g. in your /sys/<arch>/conf/<kernel name>
options MAXDSIZ=(2000UL*1024*1024)
But I dont know, if that is a good idea... Maybe you should use
nextboot(8) in case your box does not like the new kernel... :-)

see /boot/defaults/loader.conf or man loader.conf. I would also suggest
not using your entire amount of memory in these settings. Freebsd was
crashing when i set these limits to 3G. 6.0-RELEASE #0 SMP kernel.
This box has 3G physical memory.
kern.dfldsiz=2147483648 # Set the initial data size
limit # 2G
kern.dflssiz=2147483648 # Set the initial stack size
limit # 2G
kern.maxdsiz=2147483648 # Set the max data
size # 2G
kern.maxtsiz=2147483648 # Set the max text
size # 2G
kern.maxssiz=2147483648 # Set the max stack
size # 2G
