buffindexed: no space left for buffer

[Kazunori HASEGAWA]

hello,

I've got some problems on my server running INN 2.3.2.
Here's the result of 'inndf -o';
99 % overview space used

I think the buffer is full and I need to create new one.
but I don't know what to do first. Could you help me?

error messages from log file;
