I don't think there is any bug at all. There is just the annoyance of not knowing exactly what memory is available; AFAIK you can not know that until you try to use it.
The slab is not really a cache. In some cases it can be a cache, but generally it isn't. It's regular kernel memory allocations. (like a "malloc" for kernel use) Sometimes some of these allocations will be freed when you need memory for something else. There is no way to tell. Unless performance is going bad, there really isn't any reason to worry. Memory usage values are never going to be perfect or even close; getting them closer would cost performance! -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
