There has recently been some rearranging of items in the AOLserver trackers, which is probably why the links in older posts are broken. I suspect you are seeing the problem caused by the original version of this patch:
Feature Request: [ 474259 ] ns_uuencode patch
http://sourceforge.net/tracker/index.php?func=detail&aid=474259&group_id=3152&atid=353152
and a version which shouldn't crash the server but may have other issues is at:
Feature Request: [ 698741 ] New ns_uuencode patch
http://sourceforge.net/tracker/index.php?func=detail&aid=698741&group_id=3152&atid=353152
