[Avodah] Parthat Behaalotcha "600,000 Ragli"

[Henry Topas]

Moshe Rabbeinu, in discussing the notion of feeding the complaining B'nai
Yisroel, uses the number 600,000, seemingly as the number of those to whom
the Ribono Shel Olam would have to feed meat.  Rashbam notes that this is
exclusive of women and children.  

I am looking for other sources (in the M'forshim or elsewhere) which would
reconcile this number as being only the approximation of the males between
20 and 50 in the census taken in Parshat Bamidbar with the following
question:  

Were the complaints regarding food limited to the males as the only ones
requesting to be fed something other than manna?  

I have seen one approach that this was only the erev rav but it is not
clear.

Thank you,

Cantor Henry Topas
