Probably because of etag module.

Also,
if ($uri ~* (\.(js|swf|ico|gif|jpg|jpeg|png|css|xml|mp3))$) {

means that you should use

location ~* (\.(js|swf|ico|gif|jpg|jpeg|png|css|xml|mp3))$) {

However, this is not cause of memory leak.

And probably, this contstruction does not work at all:

location / {
if ($request_method = POST) {
error_page 404 = /phppost;
}
if ($uri ~* \.html$) {
root /data/www/html;
return 0;
}
