once has to carefully differentiate between reserved address space
and memory used. the first happens a lot on "RDMA" infrastructures
like infiniband or myrinet. a process may show several GB under VIRT
(when monitoring with top) but the more important columns are
RES and DATA (which may need to be explicitly enabled) which
show the resident set size and the data segment size. 

in any case, if we would know what the exact error messages are
and what the exact input was, we could do a much better guess
at what was going on.
