Thanks Steve but I still do not understand that I set all the item's expire time to '0' so,why these age will be such that stat? Does the following stats STAT items:1:number 12 STAT items:1:age 5904 mean: the slab whose classid is 1 have 12 items and this slab's next expire item will be expire in 5904 seconds? Is this right? I can not sure about it.
Help me more,thanks again 2007/8/4, Steven Grimm <[EMAIL PROTECTED]>: > > John.H wrote: > > STAT items:33:number 100 > > STAT items:33:age 6150 > > > > And I want to know what does the age mean? > > It is the age in seconds of the item that will expire next in each slab > class.
