Set the USRSTACK to more the 0x0e000000, by editing /sys/arch/amiga/inc=
lude/vmparam.h,
then recompile the kernel.

You might also need to set=20

options	NKMEMCLUSTERS=3D512=20

or even bigger.

Contrary to popular believe, your Problem is NOT directly connected to
more than 64 MB of RAM.

Rather, anything that makes the kernel virtual size too big (like: lots
of options / drivers compiled in, lots of non-Z2 Zorro boards inserted,
a big file buffer cache) might trigger it.

The file buffer cache scales, normally, to between 5 and 10% of total
memory, so your memory indirectly triggers the problem.

=46ix: Compile a kernel with bigger NKMEMCLUSTERS.
