Not reproducible. The latest PHP CVS with AOLserver 3.3.1 on FreeBSD 4.3-BETA does
not exhibit this behaviour.

When I using PHP4 in AOLSerevr3.2 at FreeBSD,
It seems to get memory leak when I using fsockopen() & fclose(),
and the memory usage is gettiing bigger & bigger....
configure option --with libgcc.
