A large number of page-ins may be a symptom of a large number of recent page-outs. To find out what process is reading these pages in, check the resident size of the processes you are running, and see which ones are increasing in size.
A large number of page-ins may also occur when a large process has just stopped, and the kernel decides to fill that space with memory pages owned by other processes. Make sure that an important process hasn't died unexpectedly.
