Subject: HTTP requests per minute: 507.4

Hi there!

Why is it that when I restart squid and it runs for about an hour or less, that my HTTP requests per minute: reachs a very high max value and then comes back down?

I was doing about 336 request per min.

I stop squid and restart it. It then when up to HTTP requests per minute: 507.4

How can I prevent this problem?

Could it be a memory problem?

Here is the top command output:
