PAE: Cannot fork

	I have a problem with FreeBSD 7.x 32bit running the standard PAE kernel on a dell R210 server with 16GB of RAM. All servers spec'ed like this have the same identical problem and it is not a hardware issue because all memory tests have been negative.

	basically the issue comes after PAE kernel has been compiled and the system outputs all the time the following:

	cannot fork kstack allocation failed or vm_thread_new: kstack allocation failed

	Since, this is a dell server there is basically nothing that I can disable in BIOS, so perhaps someone knows what loader options do I need to tweak the kernel and stop this from happening.
