How to empty Gnus newsgroups caches ?

[Ashish SHUKLA]

Hi

I'm using Leafnode as a NNTP server for my Gnus. And, I've recently mkfs'd my
news spool, And I've also removed .newsrc files, but when I load Gnus, I still
see Gnus showing old message count in *Group* buffer. To me, it looks like
Gnus has cached newsgroup information somewhere also. So, is there any way to
empty Gnus's newsgroup cache ?

Thanks
