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.
