Can you reproduce the crash using PHP's CLI sapi? The backtrace does not indicate the the crash is the result of PHP code, but rather something in Apache code(?). ------------------------------------------------------------------------ [2003-02-04 14:20:57] ntrujillo@cox.net Spider, The Stable branch is still breaking somewhere along the ftp ftp_*list functions in FreeBSD5.
