buffer pool and dbimport (11.70FC5)

Hi, I'm facing a problem and i don't understand how is it possible ... I'm loading (dbimport) a big table (> 3 Million records) and my buffer pool becomes quickly full (700000 buffers with LRU min = 0.50 and max 1.00). Checkpoint is not trigger until CKPINTVL (180) and you can image how long is the checkpoint process (see onstat -h ckp below ...) Can someone explain me that because on 9.30 i've never seen that ?
