Odd. The docs are slightly incorrect the max= value should be 5 not 20.

But the startup should be 0 in all Squid-3.2+ like you say. Are you
applying any patches to external_acl.cc or helper/ChildConfig.cc ?

That is only logged when helpers exit by themselves. Properly
functioning helpers are required to always remain active and listening
for more lookups from Squid. Only when Squid terminates the stdin
channel should the helper exit.

I hope there is no difference. Perl scripts are supposed to work the
same on any OSthat supports Perl.
