[squid-users] 2 squid instances

I have 2 squid instances.

Both are taking the same amount of connections, and both are
connecting to the same exact pool of origins via a lb.

  2344 root 13G 13G cpu1 0 0 4:03:10 25% squid/1
  2096 root 13G 13G sleep 31 0 4:47:22 9.2% squid/1

After about 14 hours of runtime, the instances hit 25% utilization,
and then never seem to restabilize.

This is all I see in my cache.log for the instance that is maxed out:

The box is a 2 cpu dual core, so each squid instance maxes out at 25% cpu.
The are strictly in memory cache (no disk), and they each have 9G of
RAM per instance.

Can someone give me an idea of what is happening?

Thanks.
