having installed,

CacheRouter 6.x-1.0-beta8

in a,

Drupal 6.12

installation, when i nav to, e.g.,

https://www.mydomain.net/main/admin/build/modules

at the top of the page, i'm getting a list of,

* warning: Invalid argument supplied for foreach() in /home/mydomain/public_html/main/sites/default/modules/cacherouter/engines/apc.php on line 121.
* warning: Invalid argument supplied for foreach() in /home/mydomain/public_html/main/sites/default/modules/cacherouter/engines/apc.php on line 121.

* warning: Invalid argument supplied for foreach() in /home/mydomain/public_html/main/sites/default/modules/cacherouter/engines/apc.php on line 121.

where the list continues to grow in number on some, not all, subsequent visits.

fwiw, i've

Apache/2.2.11 + mod_fastcgi/2.4.6
php 5.2.9 runs as fcgid
apc 3.1.2

I got the same problem with the Drupal 5 version.
When you lookup what's in $lookup, you will see, it's boolean FALSE. On the description of the function you will find "Returns either the cache object or FALSE on failure", so all is right.

You have 2 options to solve this: change the error reporting setting of php, or like me, add an if around the line 121:

     // added to remove the warning, when $lookup === FALSE
      if ($lookup !== FALSE) {
	      foreach ($lookup as $k => $v) {
    	    if (substr($k, 0, strlen($key) - 1)) {
        	  apc_delete($k);
	          unset($lookup[$k]);  
    	    }
      	}
      }
