That does seem odd. The port build does say that open office
needs higher system limits:
<Openoffice needs a larger stack- and
<datasize to build. Check your limit
<settings and add this to your KERNEL
<configuration if necessary:
<
<options MAXDSIZ="(1024*1024*1024)"
<options MAXSSIZ="(256*1024*1024)"
But it doesn't make much sense. A 64 megabyte stack ought
to be plenty, as should the default 512MB data size.
It should be noted that mmap() uses whatever VM space
remains after MAXDSIZ and MAXSSIZ have been reserved, so
increasing MAXDSIZ reduces the amount of VM available
to mmap(). Still, a 1 GB MAXDSIZ should not result in
system utilities / servers running out of mmap() space!
Userland has 3G of VM space to play with.
