I'm having trouble with the lang/php5 make on a dual cpu sparc20 w/ 512M
of RAM and 1G of swap.  The make crashes out with a memory allocation
error while trying to allocate a single 64M block on top of earlier 2M
worth of allocations.

Because there's plenty of memory/swap on my system (and I tried this
once w/ every extraneous process killed and it still had the memory
allocation error) I assume this is due to some kernel tuning parameter
re how much memory a single process can allocate, or perhaps it is due
to a wired in 32bit memory allocation limit that cannot be worked
around.

? Does someone know off the top of their heads what tuning parameter is
involved?

Thanks,
