weird mem usage

[Mike Leong <leongmzlist@xxxxxxxxx>]

Hi,

Squid is flushing the mem cached objs once it hits a certain 
threshhold.  See my attachment for the graph.

system: 4GB of ram

cache mem set to 2GB
has about ~12,944,329 objects in each cache, and is increasing daily

any ideas why squid is behaving like this?
