Note that linux counts mapped files as RSS if they're paged in. Maybe try
something like summing up the various different memory types from
/proc/<pid>/smaps ? eg:
$ cat /proc/$(pgrep java)/smaps | perl -mData::Dumper -n -e 'if
(/(.+):\s+(\d+) kB/) { $sum{$1} += $2; } END { print
Data::Dumper::Dumper(\%sum); }'
$VAR1 = {
'Rss' => 475148,
'Shared_Dirty' => 20,
'Locked' => 0,
'MMUPageSize' => 2128,
'Shared_Clean' => 9660,
'Size' => 2860292,
'Private_Dirty' => 459248,
'KernelPageSize' => 2128,
'Swap' => 0,
'Referenced' => 472196,
'Anonymous' => 459240,
'Pss' => 465681,
'AnonHugePages' => 444416,
'Private_Clean' => 6220
};
