I don't think so. These settings are supposed to be expressed in
kilobytes, so the values you give above would be on the close order of
9 petabytes, which seems a little too big compared to the memory size
usually available on today's computers.

Try adding the following to your vimrc:

" make sure the memory sizes are set to a "reasonable" value
" but allow an explicit setting up to 2½ times our default
if &maxmem > 5000000
set maxmem=2000000
endif
if &maxmemtot > 5000000
set maxmem=2000000
endif

Best regards,
Tony.
