commBind: Cannot bind socket

["Markus Moeller" <huaraz@xxxxxxxxxxxxxxxx>]

When I try to start an external acl helper I get the following errors:

2012/04/06 19:03:27| helperOpenServers: Starting 5/5

Any idea for what I need to look ?

I use squid3-3.1.16-2.3.1.x86_64 on OpenSuse 12.1. My config is:
