[squid-users] Engine ... is idle.

Hi,

I have one squid 3.1.11 running at 100% cpu load with virtually no traffic. The squid is on a box with two parallel forward squid. The other squid runs normally. The only difference between the two squid is they listen on different port and use different cache directory, log and pid files.

Even with the high cpu load, the little traffic passing through both squid was processed normally.

I turned on debug on both squid, the one with higher load logs the following lines far more frequently than the other normal running squid.

I have been running this setup for a while. This is the first time we observe the problem. Is there any further debug I can do to trace down the problem? I am afraid if I restart the squid, the problem will be gone.
