Greetings,
Hopefully, I can save someone a few hours of heartache.
Summary:
If you plan to use squid on solaris 10 x86, and configure to use
/dev/poll, make sure its patched.
Thanks everyone for reading the spam below if you did.

Also,
Just killed all connections to squid process. CPU still pegged at 15%
and decreasing

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 00 4:03:10 25% squid/1
2096 root 13G 13G sleep 310 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.

Greetings,
Also, here is some truss output to show what the process is doing.
