[squid-users] Number of clients accessing cache"-Output with "squidclient mgr:info" not increasing with Squid 3.3.4

[Tom Tom]

Hi
With squid 3.3.4 (4 workers configured) the value "Number of clients
accessing cache" within the output of "squidclient mgr:info" is not
increasing (always 0). Is this a known problem or probably a bug?

Thanks a lot.
Tom
