There are two known causes to this:

a) You cache contains mostly very small objects, pushing the average
object size below store_avg_object_size / 2.
Fix: reconfigure store_avg_object_size in squid.conf to a smaller value
(use cachemgr to check your current value). The penalty from configuring
it to low is a slightly higher memory use.

b) You have a very small cache, and a very busy Squid.
Fix: Increase the cache size, and configure a smaller expected average
object size.
