First external_acl by myself : FATAL: the myexternalacl hepers ate crashing too rapidly, need help!

["casfre@xxxxxxxxx" <casfre@xxxxxxxxx>]

Hi,

    Sorry about last incomplete message. To many keyboards here. :-(

    I am trying to make my first external_acl_helper, but I am having problems.

    My script ( based on examples from squid-user mail list archive):

   #!/usr/bin/perl
   $|=1;
   while ( my $parms = <STDIN> )
   {
        print "OK\n";
   }

   squid.conf

    external_acl_type myexternalacl %SRC %LOGIN
/usr/local/squid/libexec/script.pl
    acl testing external myexternalacl
    (There is no ACL using the helper, for awhile, because it is not
working anyway )

   cache.log

   WARNING: myexternalacl #10 (FD45) exited
   (there are 5 lines, changing just # and FD)
   Too few myexternalacl processes are running
   FATAL: The myexternalacl helpers are crashing too rapidly, need help.
   Squid Cache (Version 2.6.STABLE13): Terminated abnormally.


   Could someone help me? Tips, URLs for reading, anything will be welcome.

    Thank you for your attention.

Regards,

Freitas
