There is a configuration setting which saves posted files to disk.
You need the ns_limits maxupload to be large enough, then maxinput
(not sure which config section) sets an upper limit for in memory
data.
This gets decided in driver.c, around line 1892:
1891 max = connPtr->roff + connPtr->contentLength + 2;
1892 if (max < connPtr->drvPtr->maxinput) {
1893 /*
1894 * Content will fit at end of request buffer.
1895 */
...
1899 } else {
1900 /*
1901 * Content must overflow to a temp file.
1902 */
1903
1904 connPtr->flags |= NS_CONN_FILECONTENT;
1905 connPtr->tfd = Ns_GetTemp();
1906 if (connPtr->tfd < 0) {
1907 return E_FDAGAIN;
1908 }
