  The intend of a polygraph setup is that your robots and severs
should not run on the same box where SQUID resides.

The SQUID box, is the taget of the test however, since in a correct setup,
all requests to the servers from the robots goes thru SQUID.

Polygraph, poses firm load on the 'network stack' of any machine,one
of the things to look at is that the ip local port range, may need increasing
, for instance.

Any quick search on GOOGLE with those keywords, will return links to
you, as how to do that.
FD's and max open files, may also need to be increased.

Also checkout :

         # dmesg

on the nodes where the robots are trying to do their work, I once
got "Out of socket memory" ; no so ease to resolve, as it may need
further kernel changes and or changes of kernel parameters.
