You are about a year behind in kernel patches. There is one patch
that addresses similar problems. I'd recommend installing all of
the new patches. This bug seems to be relevant:

One thing that seems to have solved our hang and stall problems is
to set `pg_contig_disable=1' in the kernel. I believe that only
systems with Niagara CPUs are affected. It has to do with kernel
code for handling two different sizes of memory pages. You can find
more information here:

Also, open a support case with Sun if you haven't already.
