php session不自动销毁

服务器环境:win2003 + IIS + php5.3

php session 配置如下:

Directive Local Value Master Value
session.auto_start Off Off
session.bug_compat_42 Off Off
session.bug_compat_warn Off Off
session.cache_expire 180 180
session.cache_limiter nocache nocache
session.cookie_domain no value no value
session.cookie_httponly Off Off
session.cookie_lifetime 0 0
session.cookie_path / /
session.cookie_secure Off Off
session.entropy_file no value no value
session.entropy_length 0 0
session.gc_divisor 100 100
session.gc_maxlifetime 1440 1440
session.gc_probability 1 1
session.hash_bits_per_character 5 5
session.hash_function 0 0
session.name PHPSESSID PHPSESSID
session.referer_check no value no value
session.save_handler files files
session.save_path D:\phptemp D:\phptemp
session.serialize_handler php php
session.use_cookies On On
session.use_only_cookies On On
session.use_trans_sid 0 0

现在的问题是用户登录后就能一直在线,临时目录下的session文件不能自动销毁,越积越多,最后把服务器拖垮了。
奇怪的是同样的配置在另外一台服务器上就没问题,应该是系统设置方面的问题,不涉及到程序开发,请有运维经验的高人指点?

你改变了 session.save_path 还能垃圾回收吗?
我的经验是 session.save_path 为操作系统的临时目录时(c:\windows\temp)才能回收
